totalTemperature

Description

The totalTemperature is a fixed-value boundary condition that sets the static temperature from a definition of the total temperature.

The condition sets the temperature at the patch $T_p$ based on a specification of the total temperature, $T_0$:

$$T_p = \frac{T_0}{1 + \frac{\gamma - 1}{2 \gamma} \psi \mag{\u}^2}$$

where:

Property	Description
$T_p$	Temperature at the patch
$T_0$	Total temperature
$\gamma$	Heat capacity ratio
$\psi$	Compressibility
$\u$	Velocity

Usage

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

Boundary file

<patchName>
{
    type            patch;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type            totalTemperature;
    gamma           <scalar>;
    T0              <scalarField>;

    // Optional entries
    U               <word>;
    phi             <word>;
    psi             <word>;

    // Inherited entries
    ...
}

where:

Property	Description	Type	Required	Default
type	Type name: totalTemperature	word	yes	-
gamma	Heat capacity ratio	scalar	yes	-
T0	Total temperature field	scalarField	yes	-
U	Name of velocity field	word	no	U
phi	Name of flux field	word	no	phi
psi	Name of compressibility field	word	no	none
