Abstract

The mesoscopic mathematical model of flow in thin channel with rough walls in the 2D approach is proposed. The model is based on the Lattice-Boltzmann numerical method. The measured roughness profiles were used in numerical experiments. The effect of the surface roughness upon leakage is shown.
