externalWallHeatFluxTemperatureFvPatchScalarField: Added "power" heat source option

Browse Source 
by combining with and rationalizing functionality from
turbulentHeatFluxTemperatureFvPatchScalarField.
externalWallHeatFluxTemperatureFvPatchScalarField now replaces
turbulentHeatFluxTemperatureFvPatchScalarField which is no longer needed and has
been removed.

Description
    This boundary condition applies a heat flux condition to temperature
    on an external wall in one of three modes:

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

    where:
    \vartable
        Q  | Power [W]
        q  | Heat flux [W/m^2]
        h  | Heat transfer coefficient [W/m^2/K]
        Ta | Ambient temperature [K]
    \endvartable

    For heat transfer coefficient mode optional thin thermal layer resistances
    can be specified through thicknessLayers and kappaLayers entries.

    The thermal conductivity \c kappa can either be retrieved from various
    possible sources, as detailed in the class temperatureCoupledBase.

Usage
    \table
    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 |
    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 |
    \endtable

    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            externalWallHeatFluxTemperature;

        mode            coefficient;

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

        kappaMethod     fluidThermo;

        value           $internalField;
    }

Description
This boundary condition supplies a heat flux condition for temperature
on an external wall. Optional thin thermal layer resistances can be
specified through thicknessLayers and kappaLayers entries for the
fixed heat transfer coefficient mode.
This boundary condition applies a heat flux condition to temperature
on an external wall in one of three modes:
The condition can operate in two modes:
- fixed heat transfer coefficient: supply h and Ta
- fixed power: supply Q
- fixed heat flux: supply q
- fixed heat transfer coefficient: supply h and Ta
where:
\vartable
h | heat transfer coefficient [W/m^2/K]
Ta | ambient temperature [K]
q | heat flux [W/m^2]
Q | Power [W]
q | Heat flux [W/m^2]
h | Heat transfer coefficient [W/m^2/K]
Ta | Ambient temperature [K]
\endvartable
For heat transfer coefficient mode optional thin thermal layer resistances
can be specified through thicknessLayers and kappaLayers entries.
The thermal conductivity \c kappa can either be retrieved from various
possible sources, as detailed in the class temperatureCoupledBase.

Class
Foam::compressible::turbulentHeatFluxTemperatureFvPatchScalarField
Description
Fixed heat boundary condition to specify temperature gradient. Input
heat source either specified in terms of an absolute power [W], or as a
flux [W/m^2].
The thermal conductivity \c kappa can either be retrieved from various
possible sources, as detailed in the class temperatureCoupledBase.
Usage
\table
Property | Description | Required | Default value
heatSource | 'power' [W] or 'flux' [W/m^2] | yes |
q | heat power or flux field | yes |
Qr | name of the radiative flux field | yes |
value | initial temperature value | no | calculated
gradient | initial gradient value | no | 0.0
kappaMethod | inherited from temperatureCoupledBase | inherited |
kappa | inherited from temperatureCoupledBase | inherited |
\endtable
Note: If needed, both 'value' and 'gradient' must be defined to be used.
Example usage:
\verbatim
hotWall
{
type compressible::turbulentHeatFluxTemperature;
heatSource flux;
q uniform 10;
kappaMethod fluidThermo;
kappa none;
Qr none;
}
\endverbatim
