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.

Usage

Example of the boundary condition specification:

<patchName>
{
    // Mandatory entries
    type            alphatFilmWallFunction;

    // Optional entries
    filmRegion      <word>;
    B               <scalar>;
    yPlusCrit       <scalar>;
    Cmu             <scalar>;
    kappa           <scalar>;
    Prt             <scalar>;

    // Inherited entries
    ...
}

where the entries mean:

Property	Description	Type	Reqd	Deflt
`type`	Type name: alphatFilmWallFunction	word	yes	-
`filmRegion`	Name of film region	word	no	surfaceFilmProperties
`B`	Model coefficient	scalar	no	5.5
`yPlusCrit`	Critical y+ for transition to turbulence	scalar	no	11.5
`Cmu`	Empirical model coefficient	scalar	no	0.09
`Prt`	Turbulent Prandtl number	scalar	no	0.85
`kappa`	von Karman constant	scalar	no	0.41
