Rough Wall Modification of Two-Layer k-e

Abstract
A formulation is developed to apply the two-layer k-ε model to rough surfaces. The approach involves modifying the ℓv formula and the boundary condition on k. A hydrodynamic roughness length is introduced and related to the geometrical roughness through a calibration procedure. An experiment has been conducted to test the model. It provides data on flow over a ramp with and without surface roughness.
