Detailed Description

Applies a heat flux condition for a specified faMesh region to temperature on an external wall for compressible flows in one of three modes:

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]

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

Usage

Minimal example by using constant/faOptions:

externalHeatFluxSource1
{
    // Mandatory entries (unmodifiable)
    type            externalHeatFluxSource;

    // Mandatory entries (runtime modifiable)
    mode            <mode>;

    // Optional entries (runtime modifiable)
    Ts              <TshellName>;
    emissivity      0;

    // Conditional mandatory entries (runtime modifiable)

        // when mode=power
        Q           1.0;

        // when mode=flux
        q           1.0;

        // when mode=coefficient
        h           1.0;
        Ta          <Function1>;

    // Mandatory/Optional (inherited) entries
    ...
}

where the entries mean:

Property	Description	Type	Reqd	Dflt
`type`	Type name: externalHeatFluxSource	word	yes	-
`mode`	Mode of heat flux condition	word	yes	-
`Ts`	Name of shell temperature field	word	no	Ts(suffix)
`emissivity`	Surface emissivity for radiative flux to ambient	scalar	no	0
`Q`	Fixed heat power [W]	Function1	cndtnl	-
`q`	Fixed heat flux [W/m2]	Function1	cndtnl	-
`h`	Heat transfer coefficient [W/m^2/K]	Function1	cndtnl	-
`Ta`	Ambient temperature [K]	Function1	cndtnl	-

The inherited entries are elaborated in:

Options for the mode entry:

      power       | Use fixed power (supply Q)
      flux        | Use fixed heat flux (supply q)
      coefficient | Use fixes heat transfer coefficient (supply h and Ta)

Naming changes from 2506 and earlier:

Keyword	Description	Keyword (old)	Deflt (old)
`Ts`	Temperature (shell)	T	T

If Ts is missing, the keyword T is still accepted.
