Abstract

The model of a perfect gas is used in a numerical simulation of unsteady effects in a viscous shock layer near the stagnation streamline near the front part of a rotating blunt body in an inhomogeneous external flow with pressure difference ΔP t8, temperature difference ΔT t8, and vorticity difference ΔΩ. The evolution of nonlinear disturbances due to the passage of a heated region and a change of the injection regime is followed. A divergence finite-difference scheme of second order of approximation across the shock layer, realized by vector sweeps with allowance for the boundary conditions on the surface of the body and behind the separated bow shock wave, is used.
