Simulation of the generation of turbulence motion in edge wakes

Abstract

The process of generating turbulence in edge wakes has been simulated and the results of the simulation are presented. The proposed mathematical model follows from a special procedure, which aims to average the flow parameters on scales comparable with the free path of molecules. The examined mechanism of generating turbulence is described by an expended set of Euler and Navier-Stokes nonstationary equations, with additional dispersive summands of the third order, which are obtained, if one uses the averaging procedure. The basic hydrodynamic equations are integrated by means of the well known Godunov procedure of the second order. The calculated averaged perfor mances of the turbulent flows agree with the experimental data.
