alphatPhaseChangeJayatillekeWallFunction

Description

The compressible::alphatPhaseChangeJayatillekeWallFunction is a boundary condition that provides a thermal wall function for turbulent thermal diffusivity (usually alphat) based on the Jayatilleke model for the Eulerian multiphase solvers.

Usage

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

Boundary file

<patchName>
{
    type            patch;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type            compressible::alphatPhaseChangeJayatillekeWallFunction;

    // Optional entries
    Prt             <scalar>;
    Cmu             <scalar>;
    kappa           <scalar>;
    E               <scalar>;

    // Inherited entries
    ...
}
