This boundary condition applies a heat flux condition to temperature on an external wall in one of three modes:
where:
= | Power [W] | |
= | Heat flux [W/m^2] | |
= | Heat transfer coefficient [W/m^2/K] | |
= | Ambient temperature [K] |
For heat transfer coefficient mode optional thin thermal layer resistances can be specified through thicknessLayers and kappaLayers entries.
The thermal conductivity kappa
can either be retrieved from various possible sources, as detailed in the class temperatureCoupledBase.
The ambient temperature Ta is specified as a Foam::Function1 of time but uniform is space.
Property | Description | Required | Default value |
---|---|---|---|
mode | 'power', 'flux' or 'coefficient' | yes | |
Q | Power [W] | for mode 'power' | |
q | Heat flux [W/m^2] | for mode 'flux' | |
h | Heat transfer coefficient [W/m^2/K] | for mode 'coefficent' | |
Ta | Ambient temperature [K] | for mode 'coefficient' | |
thicknessLayers | Layer thicknesses [m] | no | |
kappaLayers | Layer thermal conductivities [W/m/K] | no | |
relaxation | Relaxation for the wall temperature | no | 1 |
emissivity | Surface emissivity for radiative flux to ambient | no | 0 |
qr | Name of the radiative field | no | none |
qrRelaxation | Relaxation factor for radiative field | no | 1 |
kappaMethod | Inherited from temperatureCoupledBase | inherited | |
kappa | Inherited from temperatureCoupledBase | inherited |
Example of the boundary condition specification:
<patchName> { type externalWallHeatFluxTemperature; mode coefficient; Ta constant 300.0; h uniform 10.0; thicknessLayers (0.1 0.2 0.3 0.4); kappaLayers (1 2 3 4); kappaMethod fluidThermo; value $internalField; }
