COMSOL plot of thermal radiation from heated surfaces -- Help please

In summary, the conversation discusses the use of an electron beam to heat the surface of a material and the need to calculate the amount of heat released and create a graph of dependence. The question is asked about which modules in COMSOL can be used for this purpose. It is mentioned that a previous article on modeling emissivity in radiative heat transfer was not helpful as the radiation in question is thermal spectra emitted by heated bodies.

Homework Statement
Is it possible in COMSOL to plot graphs of thermal radiation from heated surfaces? If yes, is it possible to do this when using the "heat transfer in solids" module, or is it necessary to connect additional modules? Thank you in advance!

How is it possible to plot thermal radiation graphs in COMSOL?
There is heating of the surface of the material using an electron beam. It is necessary to calculate how much heat will be released and build a graph of dependence. Please tell me how this can be done, which modules in COMSOL can be used?Thank you!

Thank you for your reply! We have already studied this article earlier, but it does not give us the right answer. The radiation we are interested in is rather thermal spectra. They are emitted by bodies having a temperature greater than 0 K, that is, by different heated bodies, which is why it is called thermal.
 

1. What is COMSOL plot of thermal radiation from heated surfaces?

COMSOL plot of thermal radiation from heated surfaces is a graphical representation of the distribution of thermal radiation emitted from a heated surface. It is generated using the COMSOL Multiphysics software, which is a powerful tool for simulating and analyzing various physical phenomena.

2. How does the COMSOL plot of thermal radiation from heated surfaces work?

The COMSOL plot of thermal radiation from heated surfaces works by solving the heat transfer equations and taking into account the properties of the heated surface, such as its temperature, emissivity, and geometry. The software uses finite element analysis to calculate the radiative heat transfer between the heated surface and its surroundings, and then generates a visual representation of the results.

3. What are the benefits of using COMSOL plot of thermal radiation from heated surfaces?

Using the COMSOL plot of thermal radiation from heated surfaces allows for a better understanding of the heat transfer processes involved in a system. It also provides a way to optimize the design of heated surfaces and predict their thermal performance. Additionally, the software allows for easy comparison of different design options and can save time and resources in the design process.

4. How accurate is the COMSOL plot of thermal radiation from heated surfaces?

The accuracy of the COMSOL plot of thermal radiation from heated surfaces depends on the accuracy of the input data and the assumptions made in the simulation. The software uses advanced mathematical models and algorithms, but it is always important to validate the results with experimental data.

5. Can the COMSOL plot of thermal radiation from heated surfaces be used for different materials?

Yes, the COMSOL plot of thermal radiation from heated surfaces can be used for different materials as long as their thermal properties, such as emissivity and thermal conductivity, are known. The software also allows for the simulation of multiple materials in a single model, making it a versatile tool for analyzing complex systems.
