We work with the system of equations describing the non-stationary compressible turbulent multicomponent flow in the gravitational field. We assume the mixture of perfect inert gases. The flow over rough terrain is simulated with the use of the finite volume method. The modified Riemann problem is solved at the boundary faces. The roughness of the surface is simulated using the alteration of the specific dissipation at the wall, and with the use of the wall functions. Velocity profile is compared with the experimental results. Own-developed computational code is used.
