ABSTRACT

Based on the dynamic equation of structure function of resolved scale turbulence a subgrid eddy viscosity model is established for anisotropy turbulence. Since the correct energy transfer between resolved and unresolved scale turbulence is involved in the model the subgrid eddy viscosity model is capable to predict anisotropic turbulence successfully, e.g. rotating turbulence and plane shear turbulence.
