摘要: Dynamic renormalization group methods are applied to the derivation of subgrid scale (SGS) closures for high Reynolds number (R) turbulence. The resulting SGS attractive in that they do not require additional ad hoc treatment wall layers and may be used derive more complicated physical problems, such as flows with buoyancy effects or chemical reactions, without arbitrary modelling parameters. Numerical experiments these turbulent channel flow at show give results reasonable agreement experiment.
