Numerical Computation of Turbulent Shear Flows

Abstract

In this paper, the authors report simulations of turbulent shear flows by numerical solution of the three-dimensional Navier-Stokes equations. This approach provides several advantages over more conventional approaches. First, the complete flow field is obtained at all times so that detailed flow characteristics may be obtained that would be difficult to measure in the laboratory. Second, initial conditions can be accurately controlled so that their effect may be determined. Third, numerical simulations are convenient experiments to assess the effect of various physical processes, like chemical reactions, on turbulence and vice versa. Fourth, the simulations results can be used to test and suggest various statistical hypotheses involved in turbulence models and theories.
