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.

This application was built using the following:

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product's capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
