Simulation of two-dimensional turbulence in a planar channel

Abstract

A study is made of the two-dimensional flow of an incompressible viscous fluid in a planar channel at supercritical Reynolds number Re = 104. Calculation of the flow over an appreciable time interval leads to the establishment of a statistically steady flow regime and stabilization of its averaged characteristics (the profile of the mean velocity, the mean pressure gradient, the pulsation energy, etc.). The calculations show that numerical simulation of turbulent flow of an incompressible fluid on the basis of the Navier-Stokes equations leads to qualitatively correct characteristics of this flow regime.
