#include <incompressibleRASModels/nutRoughWallFunctionFvPatchScalarField.H>


Detailed 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)
