Description
|
||||||
|
Calculates and writes the heat flux in incompressible flow with Boussinesq's
|
||||||
|
buoyancy assumption (e.g. buoyantBoussineqSimpleFoam) for all patches as the
|
||||||
|
boundary field of a volScalarField and also prints the integrated flux for
|
||||||
|
all wall patches.

Foam::fixedHeatFluxTemperatureFvPatchScalarField
|
||||||
|
|
||||||
|
Description
|
||||||
|
|
||||||
|
Fixed temperature flux boundary condition. Assumes incompressible turbulent
|
||||||
|
flow. The normal temperature gradient is calculated as:
|
||||||
|
|
||||||
|
snGrad(T) = q/(kappaEff*rhoRef*c)
|
||||||
|
|
||||||
|
where:
|
||||||
|
- q is the prescribed heat flux [W/m^2],
|
||||||
|
- kappaEff is the effective diffusivity field: nu/Pr + nu_t/Pr_t,
|
||||||
|
- Pr and Prt are laminar and turbulent Prandtl number read from
|
||||||
|
transportProperties dictionary
|
||||||
|
- rhoRef is the reference density
|
||||||
|
- c is the specific heat capacity
