Detailed Description

This boundary condition provides a wall-function for the turbulent viscosity (i.e. nut) when using wall functions for rough walls, based on the turbulent kinetic energy (i.e. k). The condition manipulates the wall roughness parameter (i.e. E) to account for roughness effects.

Parameter ranges:

roughness height (i.e. Ks)= sand-grain roughness (0 for smooth walls)
roughness constant (i.e. Cs) = 0.5-1.0

Usage

Example of the boundary condition specification:

<patchName>
{
    // Mandatory entries
    type            nutkRoughWallFunction;
    Ks              uniform 0;
    Cs              uniform 0.5;

    // Inherited entries
    ...
}

where the entries mean:

Property	Description	Type	Reqd	Dflt
`type`	Type name: nutkRoughWallFunction	word	yes	-
`Ks`	Sand-grain roughness height	scalarField	yes	-
`Cs`	Roughness constant	scalarField	yes	-
