Detailed Description

This boundary condition provides a thermal wall function for turbulent thermal diffusivity (usuallyalphat) based on the Jayatilleke model for the Eulerian multiphase solvers.

Usage
Example of the boundary condition specification:
<patchName>
{
    // Mandatory entries
    type            alphatPhaseChangeJayatillekeWallFunction;

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

    // Inherited entries
    ...
}

where the entries mean:
