How we can define a convective heat flux at a boundary in COMSOL Multiphysics

In many cases we know that there is a fluid flow over a boundary of a solid body and it is needed the effect of convective heat flux be determined or examined. In this tip we will see how we can do this in an example. Heating Circuit CMS is used to illustrate this tip.

Heat Flux 1

  1. In the Physics toolbar, click Boundaries and choose Heat Flux.
  2. Select Boundaries 4 and 6–8 only.
  3. In the Settings window for Heat Flux, locate the Heat Flux section.
  4. Click the Convective heat flux button.
  5. In the h text field, type h_air.
  6. In the Text text field, type T_air.
