Detailed Description

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

Usage
Property Description Required Default value
Prt turbulent Prandtl number no 0.85

Example of the boundary condition specification: 

    <patchName>
    {
        type            alphatJayatillekeWallFunction;
        Prt             0.85;
        value           uniform 0;
    }

Note that other model constants (i.e., Cmu, kappa and E) are obtained from the corresponding turbulent viscosity boundary condition.
