Radiation in a Cavity

Application ID: 447

This model shows how to build and solve a radiative heat transfer problem using the Heat Transfer interface. In particular, this 2D model illustrates the use of the surface-to-surface radiation feature.

In this model, three surfaces form a cavity. Heat flux is set at two outer boundaries, while temperature is set on the third.

The model's simple geometry, allows a comparison of results from COMSOL Multiphysics with the theoretical solution.
