Abstract:
Turbulent motion is described by a system of parabolized Novier–Stokes equations which is closed by the $(k-\varepsilon)$ model of turbulence. In the numerical calculations performed by the method of decomposing the flow vectors, the complex pattern of the interaction between perturbation waves is shown. In addition, it is shown that the system of shock waves on a gas-dynamic site causes the production of the pulsation-motion energy and the appearance of dissipative cellular structures in the field of kinetic turbulence energy.
