TURBULENT WAKES

The report describes progress in developing model equations based on an eddy viscosity written in terms of the scalar quantities for turbulence energy and integral length scale. The turbulence model equations have been shown to adequately describe mean and turbulence properties for incompressible and compressible flat plate boundary layers. Properties of an implicit finite difference method for solving the time-dependent model equations are discussed as applied to laminar (Navier-Stokes) problems. The method appears to be stable, of second order accuracy in space and time, and well behaved in the presence of internal shocks. (Author)
