SUMMARY

The discussion focuses on calculating thermal radiation from heated surfaces using COMSOL Multiphysics. Users are seeking guidance on which specific modules to utilize for modeling emissivity and thermal spectra emitted by materials heated by an electron beam. The conversation highlights the need for accurate representation of thermal radiation, particularly for bodies at temperatures above absolute zero.

PREREQUISITES
  • Familiarity with COMSOL Multiphysics software
  • Understanding of thermal radiation principles
  • Knowledge of emissivity modeling techniques
  • Basic concepts of heat transfer and electron beam heating
NEXT STEPS
  • Explore the COMSOL Heat Transfer Module for thermal radiation analysis

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!
Relevant Equations
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.
