Detailed Description

This boundary condition applies a heat flux condition to temperature on an external wall. Heat flux can be specified in the following ways:

fixed power: supply Q
fixed heat flux: supply q
fixed heat transfer coefficient: supply h and Ta

where:

	=	Power [W]
	=	Heat flux [W/m^2]
	=	Heat transfer coefficient [W/m^2/K]
	=	Ambient temperature [K]

If more than one parameter is given then the heat fluxes are summed.

If a heat transfer coefficient is given optional thin thermal layer resistances can be specified through thicknessLayers and kappaLayers entries.

The patch thermal conductivity kappa is obtained from the region thermophysicalTransportModel so that this boundary condition can be applied directly to either fluid or solid regions.

The ambient temperature Ta is specified as a Foam::Function1 of time but uniform is space.

Usage

Property	Description	Required	Default value
`Q`	Power [W]	no	0
`q`	Heat flux [W/m^2]	no	0
`h`	Heat transfer coefficient [W/m^2/K]	no	0
`Ta`	Ambient temperature [K]	if h is given
`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

Example of the boundary condition specification:

    <patchName>
    {
        type            externalTemperature;

        Ta              constant 300.0;
        h               uniform 10.0;
        thicknessLayers (0.1 0.2 0.3 0.4);
        kappaLayers     (1 2 3 4);

        value           $internalField;
    }
