Class
    Foam::compressible::alphatJayatillekeWallFunctionFvPatchScalarField
 
Description
    This boundary condition provides a thermal wall function for turbulent
    thermal diffusivity (usually\c alphat) based on the Jayatilleke model.
 
Usage
    \table
        Property     | Description             | Required    | Default value
        Prt          | turbulent Prandtl number | no         | 0.85
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            alphatJayatillekeWallFunction;
        Prt             0.85;
        value           uniform 0;
    }
    \endverbatim
 
    Note that other model constants (i.e., Cmu, kappa and E) are obtained from
    the corresponding turbulent viscosity boundary condition.
