Class
Foam::incompressible::RASModels::nutRoughWallFunctionFvPatchScalarField
Description
Boundary condition for turbulent (kinematic) viscosity when using wall
functions for rough walls.
Manipulates the E parameter to account for roughness effects, based on
KsPlus.
- roughness height = sand-grain roughness (0 for smooth walls)
- roughness constant = 0.5-1.0 (0.5 default)
