The processes of wave formation above inhomogeneous surface

The numerical model is proposed the problem of a streamline the arbitrary form obtacle with the stratified turbulence flow on the gravitational force field. For an exact approximation the nonlinear problems for low Mach numbers, the transformation of the initial equations of the compressible gas on the basis of the separate calculation the dynamic and the hydrostatical pressure is done. It is shown, that the fictitious regions method for the calculations the flows with the complicated boundaries is more effective in comparison with the another know methods. Influence of the flow parameters on the wave generation is investigated, and the corresponding regularities are received.
