Thermal EffectsWhen thermal effects are enabled, the solver uses a temperature-based energy equation, indicating a thermal (heat) transport simulation with temperature as the primary transport scalar variable. When thermal effects are disabled, no energy equation is used, producing an isothermal flow simulation. The energy transport equation applies to non-isothermal flows, with coupling between the momentum and energy equations. In turbulent flows, the energy transport includes a turbulent heat flux based on the turbulent eddy viscosity and turbulent Prandtl number. RadiationYou may select the surface-to-surface radiation model to include radiation effects in your heat transfer simulation. This option becomes available only when you enable thermal effects. The surface-to-surface radiation model considers radiation heat transfer in an diffuse-gray enclosure. You should provide the ambient temperature for any partial enclosure in the simulation. This model also requires the computation of view factors, which characterize the proportion of radiation interchange among surfaces. To adjust settings for view factor calculation, please edit the Surface Radiation Settings feature that has been automatically generated. |
