Turbulence modeling and implementation in Navier-Stokes solvers
Abstract
A general survey on the tools available to perform basic turbulence modeling of compressible flow is given. The following topics are discussed: the basic features of compressible flows, the Cebeci-Smith-Mosinski and the Baldwin-Lomax models, and the turbulence transport equations. The topic of the second order closure is touched through the problem of the Reynolds stress modeling. It is shown that for the variable density problems, the low speed, the weakly compressible and the strongly compressible flows, must be distinguished.
