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 -
