New simulations shed light on stellar destruction by supermassive black holes

Monash University astronomers have contributed to a breakthrough in understanding the dramatic fate of stars that wander too close to supermassive black holes at the centers of galaxies.

Through innovative simulations, an international research team, led by Professor Daniel Price and former student David Liptai from the School of Physics and Astronomy has captured the complex process of how these stars are torn apart and consumed by black holes, providing new insights into the mysterious optical and UV emissions observed during these catastrophic events.

"This is the first self-consistent simulation of a star being tidally disrupted by a supermassive black hole, followed by the evolution of the resulting debris over the course of a year," Professor Price said.

"Our simulations provide a new perspective on the final moments of stars in the vicinity of supermassive black holes," he said.

"By capturing the full evolution of the debris, we can try to connect simulations to the growing number of observed star-shredding events identified with telescope surveys"

The study, published in The Astrophysical Journal Letters, is a significant step forward in astrophysics, opening new avenues for research into the behavior of matter in extreme gravitational fields and the life cycles of stars and black holes.

When a star passes too close to a supermassive black hole, the intense gravitational forces pull it apart in a process known as a tidal disruption event (TDE). The debris from the star forms a stream that eventually feeds the black hole. The debris from the star forms a swirling disk around the black hole, which emits intense radiation across the electromagnetic spectrum. However, many aspects of TDEs remain poorly understood.

The new simulations show that this debris forms an asymmetric bubble around the black hole, reprocessing the energy and producing the observed light curves with lower temperatures, fainter luminosities, and gas velocities of 10,000–20,000 km/s.

"The study helps to explain several puzzling properties of observed TDEs," Professor Price said. "A good analogy is the human body: when we eat lunch, our body temperature does not change much. This is because we reprocess the energy from lunch into infrared wavelengths.

"A TDE is similar, we mostly do not see the black hole stomach eating gas, because it is smothered by material that reemits at optical wavelengths. Our simulations show how this smothering occurs."

Other mysteries explained by the new simulations include:

Why tidal disruption events are observed at optical rather than X-ray wavelengths, where X-rays would be expected from accretion onto a supermassive black hole.

Why the temperatures observed are consistent with the photosphere of a star rather than the expected hot accretion disk.

Why observed star-shredding events are fainter than expected from models of black holes efficiently eating material.

Why the spectra of observed events find material expanding towards us at a few percent of the speed of light (10–20,000 km/s).

Just a little science-ing ...

I'm going to try to keep this short, but this is an important concept... On Thanksgiving I got a nasty steam burn and almost dropped the turkey on the floor. During the clean-up of the spilled juices my niece commented that "sometimes it seems like steam burns more than boiling water" ... this would be because it does. She's really smart and is very into science, so I was surprised she didn't know this (but then again, he was dealing with a lot in middle and high school, so maybe not so surprising?) So here's the short explanation. Going to limit this to water, and only the liquid to vapor (vaporization) and vapor to liquid (condensation) phase changes, but the concept also holds for melting and freezing, and even sublimation and deposition. Vaporization: in a liquid, water molecules have a loose association which makes them hold together, even though they can flow around each other. It takes energy to break that association... that's why you have to heat water to make it boil. When the molecules have absorbed enough energy, they can break apart and move independently. I.e, they vaporize and become a gas. The absorbed energy is called "latent heat." The thing is, the molecules "hold" this energy as long as they are in the gas phase. Condensation: When the water molecules in water vapor slow down enough to stick together, they release the energy (latent heat) they are holding. This is a LOT of energy, much more than is in liquid water that is boiling. When steam hits a veggie, or my bare skin, condensation occurs and all of that latent heat is released into the environment which can cook the veggies ... or the careless cook. Why this is important: **Evaporation is a cooling process. For water to evaporate it needs to absorb energy ("latent heat") from the environment. Thus, sweat cools the body as it dries (the water vaporizes out of it.) Sweat is at body temperature when it leaves the pores in the skin, but it cools the skin as it absorbs body heat to vaporize. Dogs pant so that water evaporating from their mouths takes body heat with it. When oceans heat because of climate change, more water evaporates, carrying energy into the atmosphere as "latent heat." **Condensation cooks. As described above, when water condenses it releases the energy it absorbed during vaporization. This released energy can be used to cook, and can also cause serious burns. In the atmosphere, when large amounts of water vapor condense, lots of energy is released at one time, which creates low air pressure, which results in strong winds, violent thunderstorms, hurricanes, etc. Hurricanes happen over warm oceans because they are powered by the energy ("latent heat") released by condensation of water in the atmosphere. (Fun fact, the insurance industry was among the first to call for mitigation of climate change -- makes sense, as they know it's going to hit them right in the bottom line.)

(Apologies to those who recognize sloppy use of terms... gonna stop now before I start geeking on adiabatic processes #storms are so cool #hot air DOES NOT rise, it's raised, OK stopping now)

Trick or Treat!

-@the-torquedork

You get the Otto cycle! This is an idealized thermodynamic cycle that most closely matches the process used in internal combustion engines. It alternates between adiabatic (no heat transfer with the environment) expansion/compression and isochoric (constant volume) heating/cooling.

[rogalion]

I absolutely love your weather rants from a fellow trans guy who's now got a special interest in meteorology. Apparently. Ahhh!!!

(THE FACT THAT IF YOU CAN SEE THE TOP OF AN ANVIL CLOUD FLATTENING MEANS YOU CAN SEE THE FUCKING TROPOPAUSE MAKES IS SO FUCKING COOL AND JUST ALFJDIDJSIDJD).

(also the lack of standardizations on soundings is kIlling me too as a self taught meteorology nerd. I would like to know For Sure if I'm looking at the saturated or dry adiabat!!!!! Ahhh!!!

Also. Plotting hodographs. *what the fuck. Why is the compass the way it is. It's UPSIDE FUCKING DOWN???* I assume there is a reason for the meteorology compass and the hodograph compass to be different but *why????*

I love the nws I do truly I would love to work for them/the NOAA and they provide basically how to read their soundings too but there's like. 2 things I'm Not 100% sure on and it's driving me mad.)

Also I'd love to see how you get from raw to tabular data to the sounding if you want, I'm honestly curious.

Also. Do you also want to launch or find a radiosonde or is that just me. I really want to launch one.

IM

this has made my fucking week istg omg omg

So another fun fact about anvil clouds and that they flatten out when they hit the tropopause because that's the no weather allowed zone is that there's something called an overshooting top where basically you get a bubble of a cloud that goes above the anvil and into the tropopause and you get that when the updraft is strong enough that it forces the clouds over the tropopause! You can see this on a skew-T because the dew point line will stay close to the temperature line through the tropopause.

I don't know a lot about hodographs just yet it's not something I've been taught much about just yet (for example I didn't know the directions are upside down from a conventional compass) but I'm sure I'll post a rant about it when I learn more LMAO.

So working for the NWS requires a few things and that's a career path I'm looking into but I've also just finished my first year in my meteorology program so we'll see what happens.

As for launching radiosondes-- I've launched several, actually!

I'm the guy with the shades (they're my normal glasses it's just sunny and I have transition lenses) and here I'm holding the balloon before we launch it.

I go to a school with a strong meteorology program in New Hampshire called Plymouth State University, and we get a LOT of chances to talk to people from the NWS and the private sector as well as learn and use very practical skills such as launching radiosondes, graphing skew-Ts by hand, and so on.

I think I've launched at least five radiosondes at this point and I'll quickly lose count in the future. But if Meteorology is a career you're interested in going for, it will in all likelihood involve seeking out a bachelor's degree at minimum which all this boils down to, hey, join us :) there are at least three trans people in my program!

for soundings also, the raw data is collected through graw's program and graphed automatically on the computer. We just have to set up the radiosonde and antenna beforehand-- it's a whole process and I'd love to explain it more in another post I think but it's pretty bland tbh haha

also for saturated vs dry adiabats: the saturated ones are weird and curvy and the dry ones are nearly straight so they're actually pretty easy to tell apart once you know, but knowing is the hard part with skew-ts for sure.

Thank you so much for this ask I'm SO HAPPY to hear you enjoy them fr fr

The Magic of Evaporative Cooling Systems

The Magic of Evaporative Cooling Systems

In the realm of cooling technologies, one system stands out for its simplicity and effectiveness: the Evaporative Cooling System. This system, also known as adiabatic cooling, is a marvel of engineering that uses the natural process of water evaporation to cool air to a comfortable temperature.Get more news about Evaporative Cooling System,you can vist our website!

The principle behind an Evaporative Cooling System is straightforward. It exploits the fact that when water evaporates, it absorbs heat from its surroundings, thereby cooling the air. This process is the same one that makes you feel cool when you step out of a shower or when sweat evaporates from your skin.

An Evaporative Cooling System typically consists of a fan and a water-soaked pad. As the fan draws air through the pad, the water in the pad evaporates, which cools the air before it is circulated throughout the space2. This simple yet effective system can significantly reduce the temperature of a room or building, making it a popular choice in hot, dry climates.

One of the key advantages of an Evaporative Cooling System is its energy efficiency. Unlike traditional air conditioning systems, which use refrigerants and consume a significant amount of electricity, an Evaporative Cooling System uses water as its refrigerant and consumes much less energy. This makes it a more environmentally friendly option for cooling.

Another advantage is that an Evaporative Cooling System adds moisture to the air, which can be beneficial in dry climates. In contrast, traditional air conditioning systems can make the air dry, which can lead to discomfort, especially for people with dry skin or respiratory issues.

Despite its many advantages, an Evaporative Cooling System is not suitable for all environments. It works best in hot, dry climates where the air has low humidity3. In humid climates, the air is already saturated with moisture, so the water in the system does not evaporate as easily, reducing the cooling effect.

In conclusion, an Evaporative Cooling System is a simple, effective, and energy-efficient solution for cooling in hot, dry climates. It uses the natural process of water evaporation to cool the air, providing comfort while consuming less energy and adding moisture to the air. However, it is not suitable for humid climates, where its cooling effect is reduced. Despite this limitation, the Evaporative Cooling System remains a testament to the power of simple, natural processes harnessed by clever engineering.

The Role of High and Low Temperature Shock Test Chambers in Material and Component Testing

The high and low temperature shock test chamber is the necessary testing equipment for metal, plastic, rubber, electronics and other material industries. It is used to test the material structure or composite material. Detect the chemical change or physical damage of the sample caused by thermal expansion and contraction in the shortest time. The high and low temperature shock test is used to assess the adaptability of the product to the sharp change of the ambient temperature. It is an indispensable test in the identification test of the equipment design and the routine test in the batch production stage. In some cases, it can also be used for environmental stress. screening test. It can be said that the frequency of application of the thermal shock test chamber in verifying and improving the environmental adaptability of equipment is second only to vibration and high and low temperature tests. The high and low temperature shock test chamber is divided into three-chamber type and two-chamber type according to the test requirements and test standards. The difference lies in the test method and internal structure. The three-chamber type is divided into a cold storage room, a heat storage room and a test room, and the product is placed in the test room during testing. The two-chamber type is divided into a high-temperature room and a low-temperature room. The high and low temperature switching is realized through the movement of the basket driven by the motor. The product is placed in the basket and moves with the basket. Working principle of refrigeration: Both the high and low refrigeration cycles adopt the reverse Carroll cycle, which consists of two isothermal processes and two adiabatic processes. The process is as follows: the refrigerant is adiabatically compressed to a higher pressure by the compressor, which consumes work to increase the exhaust temperature, and then the refrigerant conducts heat exchange with the surrounding medium isothermally through the condenser, and transfers the heat to the surrounding medium. Finally, the refrigerant expands adiabatically through the valve to do work, and the temperature of the refrigerant decreases at this time. Finally, the refrigerant absorbs heat isothermally from the object with higher temperature through the evaporator, so that the temperature of the object to be cooled is lowered. This cycle is repeated so as to achieve the purpose of cooling. In fact, as a tool, the high and low temperature impact test chamber has different purposes in different stages of product development: 1. The engineering development stage can be used to find product design and process defects; 2. Provide basis for product finalization or design identification and acceptance decision in batch production stage; 3. When used as an environmental stress screening application, the purpose is to eliminate early failures of products. Rapid change of temperature difference in High and Low Temperature Thermal Shock Chamber: 1. The product has beautiful appearance, reasonable structure, advanced technology, excellent material selection, easy operation and reliable equipment performance. 2. Double-chamber hanging basket structure, the upper high-temperature chamber, the lower low-temperature box, the impact method is the high-temperature chamber, the low-temperature chamber stops, and the test piece is quickly moved into the high-temperature chamber by hanging and moving up and down to achieve cold and hot impact test. 3. The metering device adopted, the controller adopts a large-scale man-machine dialogue man-machine interface controller, Chinese and English LCD screens, and various complex programs can be set. The program setting adopts man-machine dialogue, which is easy to operate, easy to learn, stable and reliable. 4. Adopting advanced circulating air design, the indoor temperature is uniform and avoids any dead angle; the perfect safety protection device avoids any potential safety hazards and ensures the long-term reliability of the equipment. Test requirements: initial temperature requirements Although the general thermal shock test standard does not mention or do not make rigid regulations on the starting temperature of the thermal shock test, this is a problem that must be considered when the test is carried out, because it involves whether the test ends at low temperature or high temperature State, which determines whether the product needs to be dried, resulting in extended test time. If the test is completed and the low temperature standard test product is taken out of the High and Low Temperature Thermal Shock Chamber, it should be recovered under normal test atmospheric conditions until the sample reaches a stable temperature. This operation will inevitably cause condensation on the surface of the test sample. The effect of dew introduction temperature on the product. thereby changing the nature of the experiment. Test time requirements: 1. Stipulates the lower limit of 1h, that is, the temperature stabilization time is less than 1h, it must be 1h; if it is greater than 1h, use the time greater than 1h; 2. There are 5 time levels from 10min to 3h given in GB2423.22. According to the temperature stabilization time of the product measured by the thermal shock test chamber, the time closest to it or the optional time level is used, and the closest time is directly used. A similar time is used as the hold time; 3. In 810F method 503.4, no specific time or optional time level is specified, and the time when the product reaches temperature stabilization or the actual exposure time of the product in the environment is directly used. The performance indicators of the High and Low Temperature Thermal Shock Chamber are as follows: The accuracy is reflected by the difference between the set value and the actual detection value. The popular point is the uniformity and volatility of the chamber. The “mid-test test” uses high and low temperature resistant circulating fans in the high temperature area and low temperature area. Circulation, no matter how uniform the temperature is, it will not exceed ±3°C, and the fluctuation of the chamber is ±0.5°C (when the shock stabilizes and returns to the constant temperature in the stable chamber). The functional technical indicators of the High and Low Temperature Thermal Shock Chamber include impact sensitivity, temperature conversion speed, and accuracy. In the temperature shock test, the most critical thing is to establish the stress caused by the inconsistent thermal expansion and contraction of different materials. The actual thermal shock is most likely to occur on the outside of the product under test. Relevant data point out that it is not necessary to stabilize the temperature of the entire product, but as long as the surface and temperature of the product under test are consistent with the test temperature. High and Low Temperature Thermal Shock Chamber can be used in the temperature shock test and fast-changing temperature test in a wide range such as aviation, air space, electronic components and material research. HLST-500D has two separate chambers: high temperature chamber and low temperature chamber. HLST-500T has three separate chambers: high temperature chamber, low temperature chamber and test chamber.

Why it Is Impossible to attain Absolute Zero of a Temperature by any Physically realizable process, In order to demonstrate it why we are considering Adiabatic Demagnetization?...

• A. Pooma Begam, PG Student in St Xavier's College, Palayamkottai, Tirunelveli in Tamilnadu

The concept of absolute zero is defined as the temperature at which all matter would have zero thermal energy.

At this temperature, all substances would have zero entropy and would be in a state of perfect order.

➖ However, it is impossible to reach absolute zero through any physically realizable process, and the reason for this is related to the second law of thermodynamics.

{The second law of thermodynamics states that it is impossible to convert all of the heat energy in a system into work with perfect efficiency. In other words, there will always be some amount of energy lost as waste heat, which means that the system cannot be cooled down to absolute zero}.

Example: Adiabatic demagnetization

It is an example of a process that demonstrates this principle.

Adiabatic demagnetization is a technique used to cool a material down to very low temperatures by exploiting the fact that magnetization is a function of temperature.

• When a magnetic material is placed in a strong magnetic field, the magnetic moments of the atoms align with the field, causing the material to heat up.

• When the magnetic field is slowly reduced, the magnetic moments of the atoms will gradually become disordered, and the material will cool down.

Therefore even in adiabatic demagnetization we can achieve temperatures as low as a few micro-kelvins, but not absolute zero.

This is because the process relies on the transfer of heat energy from the material to the surroundings, and there will always be some residual heat left in the system.

Conclusion: Absolute zero can only be approached asymptotically, but it can never be reached through any physically realizable process.

CHILLERS & HEAT EXCHANGERS

One of the most crucial cooling devices used in laboratories is the chiller. A laboratory chiller's primary job is to transfer heat from one substance to other sources, such as ambient water or air. Unlike air conditioners, which cool the air, a chiller uses a compressor to cool and regulate the temperature of a liquid. In addition to the compressor, a chiller also includes a reservoir, a recirculating pump, and a temperature controller.

Different Chillers

Chillers can be categorised in a variety of ways, including functionality and mobility. Here, we've categorised chillers based on how they work.

Process water heat is absorbed by air-cooled chillers and transmitted to the outside air. They are typically employed in situations in where the heat released is unimportant. A cooling tower and condensate water pump are not required. Air-cooled chillers require less maintenance than water-cooled ones. They use 10% more energy, though.

Heat is transported from process water to a different water source, such as a river, pond, cooling tower, etc., in water cooled chillers. mostly utilised in locations where air cooled chiller heat is an issue. They are typically selected by individuals looking for the best possible power consumption efficiency due to their lower power consumption.

The operation of chillers

A laboratory chiller operates on a very straightforward principle. A fluid is put into the reservoir to be circulated, usually water or a solution of ethylene glycol and water. The reservoir is connected to the necessary machinery, and the chiller is given power. The controller controls the actions of the chiller. Users can adjust the parameters to suit their needs, such as temperature, flow, and pressure. The dangerous particles are kept out of the system by an internal strainer.

The Uses of Chillers

Many different industries employ cooling equipment. A few of the chillers' most typical uses include:

In the plastics sector, chillers are used to cool the hot plastic. The plastic that is injected, blown out of an extruder, or stamped is cooled. They are additionally employed to cool down manufacturing machinery.

Chillers are used in the printing industry to remove the heat produced by the printing rollers. When the paper exits the ink drying furnaces, they also aid in cooling it.

The high-powered electronics inside of devices like MRI and PET, utilised in the most recent diagnostic instruments, are chilled with sophisticated chillers.

Lasers and the power source that powers them are cooled by chillers.

The majority of modern equipment contain heat exchangers. Exchangers are used in a wide range of modern machines and large enterprises; they are not just found in the simplest of devices. In essence, they are parts that some machines have that allow heat to be transferred from one medium to another. They make it easier for heat to be effectively transferred from one object to another.

Heat exchanger usage

The radiators found in automobiles or air conditioners are two examples of this. Typically, a heat source moves through the exchanger, transferring heat to the water that will cool the engine. By transferring heat from the water to the air, the exchanger makes the engine cooler.

Heat exchangers are frequently used for refrigeration, air conditioning, and space heating. Power plants, chemical and petrochemical plants, oil and petroleum refineries, natural gas processors, and sewage treatment facilities are just a few of the heavy sectors that utilise this technology.

A variety of heat exchanger types are in use today. These include spiral exchangers, direct contact exchangers, HVAC air coils, shell tube exchangers, plate exchangers, adiabatic wheels, plate fins, fluid exchangers, dynamic scraped surfaces, and phase-change exchangers.

Evaporative Cooling Systems: How They Work and Their Importance

Evaporative Cooling Systems: How They Work and Their Importance Evaporative cooling, also known as adiabatic cooling, is a technique that cools air by utilizing water evaporation. Unlike traditional air conditioning systems that rely on vapor-compression or absorption refrigeration cycles, evaporative cooling systems use water as their refrigerant. Let’s explore how these systems work and why they are important.Get more news about Evaporative Cooling System,you can vist our website!

How Does Evaporative Cooling Work? Principle: Evaporative cooling works based on the principle of water evaporation. When water evaporates, it absorbs energy from the surrounding air in the form of heat. As a result, the air temperature decreases. Process: In an evaporative cooling system: Hot outside air is forced through wet cooling pads using a motor-driven fan. The cooling pads remain continuously moistened by a water pump. As the air passes through the wet pads, water evaporates, extracting heat from the air. The cooled down air is then blown into the building. Efficiency and Humidity: Direct evaporative cooling (one-stage) cools the air but increases its humidity significantly. Two-stage evaporative cooling is more efficient, producing temperatures up to 7 °C lower than direct cooling. It also contains up to 70% less humidity. Two-stage systems achieve efficiencies up to 114% of the wet bulb. Applications: Evaporative cooling is suitable for production facilities, distribution centers, and office buildings. However, direct evaporative cooling is not recommended for work and living environments due to high humidity levels. Importance of Evaporative Cooling Sustainability: Evaporative cooling, especially through indirect/direct systems, is highly sustainable and energy-efficient. Comfort: It provides a comfortable and productive climate for occupants. Energy Savings: Compared to traditional air conditioning, evaporative cooling consumes less energy. Environmental Impact: It has a lower environmental impact, as it doesn’t rely on harmful refrigerants. In summary, evaporative cooling systems offer an eco-friendly and effective way to keep indoor spaces cool. They harness the power of water evaporation to create a comfortable environment while minimizing energy usage

Understanding the Technology and Applications of Rapid Temperature Change Test Chamber

The rapid temperature change test chamber can be said to be a rapid temperature change test chamber, which is used for inspecting the various performance indicators of products in aerospace, information electronics, instruments, materials, electrical and electronic products, and various electronic components under rapid temperature changes. Rapid temperature change test chamber: mainly used for environmental simulation testing of the physical and other related characteristics of products under low and high temperature conditions in accordance with national standards or user defined requirements, Determine the performance of the product by testing the results to determine whether it meets the requirements for product design, improvement, identification, and factory inspection. The control system of the rapid temperature change test chamber needs to be equipped with safety protection measures, including: compressor overheating, overpressure, overheating, fan motor overheating, overall equipment under/reverse phase, overall equipment timing, leakage protection, overload and short circuit protection, etc. When any protection function is implemented, the operation panel will display an alarm on the LCD display screen to inform the user of any fault and cut off the main circuit power. After the fault is resolved, the device will be started. When the rapid temperature change test chamber is conducting a high temperature test, if the temperature change cannot reach the test temperature value, the electrical system can be checked and the faults can be eliminated one by one. If the heating speed is slow, the air circulation system needs to be checked to see if the regulating baffle of the air circulation is opened normally. Otherwise, the motor of the air circulation needs to be checked for normal operation. If the temperature overshoot is severe, it is necessary to adjust the PID setting parameters. Working principle of fast temperature change test chamber: Rapid temperature change test chamber: A "binary cascade air-cooled refrigeration system" composed of a fully enclosed compressor is used. The cascade refrigeration system includes "a high-temperature refrigeration cycle and a connecting container for refrigeration cycle" as an evaporative condenser, Reminder: The evaporative condenser also has the function of energy transfer, which transfers the internal thermal energy of the studio through a two-stage refrigeration system to achieve the purpose of heating up. The high and low cooling cycle of the rapid temperature change test chamber usually adopts the "reverse Karo cycle", which consists of "two isothermal processes and two adiabatic" processes. The process is as follows: the refrigerant is adiabatic compressed by the compressor to a higher pressure, consuming work to increase the exhaust temperature. After the refrigerant undergoes isothermal heat exchange with the surrounding medium through the condenser, and transfers heat to the surrounding medium, the refrigerant undergoes adiabatic expansion through the valve to do work. At this time, the temperature of the refrigerant will decrease. The refrigerant can absorb heat from higher temperature objects such as evaporators to lower the temperature of the cooled object, and this cycle repeats itself to achieve the goal of cooling. The structural characteristics of the rapid temperature change test chamber: 1. The rapid temperature change test chamber has a beautiful appearance, reasonable structure, advanced technology, and exquisite material selection. It also has simple and convenient operation performance and reliable equipment performance. 2. Adopting advanced measurement equipment and controller: adopting a large color LCD human-machine touch dialogue LCD human-machine interface controller, it is easy to operate, easy to learn, stable and reliable, and displays complete system operation status and execution and setting program curves in both Chinese and English.
