Isi artikel

A formulation is developed to apply the two - layer k – E model to rough surfaces. The approach involves modifying the L(v) 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.
