Detailed Description

This boundary condition provides a turbulent thermal diffusivity condition when using wall functions, for use with surface film models. This condition varies from the standard wall function by taking into account any mass released from the film model.


Patch usage

Property Description Required Default value
B model coefficient no 5.5
yPlusCrit critical y+ for transition to turbulent flow no 11.05
Cmu model coefficient no 0.09
kappa Von-Karman constant no 0.41
Prt turbulent Prandtl number no 0.85

Example of the boundary condition specification:

    myPatch
    {
        type            alphatFilmWallFunction;
        B               5.5;
        yPlusCrit       11.05;
        Cmu             0.09;
        kappa           0.41;
        Prt             0.85;
        value           uniform 0;
    }
