Prikl. Mekh. Tekh. Fiz. 40, No. 1, 108-114 (1999); translation in J. Appl. Mech. Tech. Phys. 40, No. 1, 93-98 (1999).
In the article under review, a turbulent motion is described by a system of parabolized Navier-Stokes equations together with the \((k- \varepsilon)\) model of turbulence. The author presents a difference system of equations and solves it by Gauss-Seidel method. He shows that the interaction of a system of intersecting supersonic jets with a hypersonic flow leads to a complex pattern of compression and rarefaction zones; the system of shock waves in the gasdynamic section of the flow causes the production of pulsation-motion energy and the appearance of dissipative cellular structures due to the kinetic turbulence energy.
