atmTurbulentHeatFluxTemperature

Description

The atmTurbulentHeatFluxTemperature is a boundary condition that provides provides a fixed heat constraint on temperature (i.e. T) to specify temperature gradient through an input heat source which can either be specified as absolute power [W], or as flux [W/m^2].

Usage

The condition requires entries in both the boundary and field files.

Boundary file

<patchName>
{
    type            patch;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type            atmTurbulentHeatFluxTemperature;
    heatSource      <word>;
    alphaEff        <word>;
    Cp0             <scalar>;
    q               <scalarField>;

    // Inherited entries
    ...
}

where:

Property	Description	Type	Required	Default
type	Type name: atmTurbulentHeatFluxTemperature	word	yes	-
heatSource	Heat source type	word	yes	-
alphaEff	Name of turbulent thermal diff. field [kg/m/s]	word	yes	-
Cp0	Specific heat capacity [m2/s2/K]	Function1<scalar>	yes	-
q	Heat source value [W (power) or W/m^2 (flux)]	PatchFunction1<scalar>	yes	-

Options for the heatSource entry:

Property	Description
power	Absolute power heat source [W]
flux	Flux heat source [W/m^2]
