Mathematical modelling of transonic flow of viscous compressible fluids in very narrow channels and gaps is one of the very topical and demanding problems of fluid dynamics today. This article presents the numerical simulations of leakage flow in a narrow channel formed by a tooth of male rotor and housing in a screw compressor. The influence of the male rotor motion on the compressible viscous flow through the clearance gap for various male rotor angular velocities is observed. The dependence of simulation results on different numerical grids is rated and the sufficiently coarse grid for obtaining reasonable results is searched. The influence of turbulence models on obtained numerical results is investigated.
