30.13. Heat Fluxes

Ansys Polyflow can integrate in the flow domain the so-called Fourier heat flux in regions where a temperature field is defined. The Fourier heat flux is defined as

(30–8)

where is the heat conductivity.

The heat flux will appear as a vector in your graphical postprocessing program. The procedure for specifying the calculation of heat fluxes is as follows:

  1. Create a new sub-task.

      Create a sub-task

    1. Select Postprocessor as the sub-task type.

    2. When prompted, enter a name for the postprocessor sub-task.

  2. In the F.E.M. Task Postprocessor menu, select Heat Fluxes.

    Ansys Polydata will tell you the subdomains where Ansys Polyflow can perform the calculation. Select the subdomains where you want Ansys Polyflow to calculate the heat fluxes. No additional parameters or boundary conditions are required.
