Detailed Description

This boundary condition provides a turbulent kinematic viscosity condition when using wall functions for rough walls, based on turbulence kinetic energy. The condition manipulates the E parameter to account for roughness effects.

Parameter ranges

roughness height = sand-grain roughness (0 for smooth walls)
roughness constant = 0.5-1.0

Usage

Property	Description	Required	Default value
`Ks`	sand-grain roughness height	yes
`Cs`	roughness constant	yes

Example of the boundary condition specification:

    <patchName>
    {
        type            nutkRoughWallFunction;
        Ks              uniform 0;
        Cs              uniform 0.5;
    }
