Examination of Diffusion Modeling Using Zero-Mean-Shear Turbulence

An examination of diffusion modeling in second-moment turbulence closures is presented. The main objectives are to gain a better understanding of the processes that are grouped into the net diffusive transport of the Reynolds stresses, Dij, and to assess existing models for Dij. The benchmark case o...

Zusammenfassung:An examination of diffusion modeling in second-moment turbulence closures is presented. The main objectives are to gain a better understanding of the processes that are grouped into the net diffusive transport of the Reynolds stresses, Dij, and to assess existing models for Dij. The benchmark case of zero-mean-shear (ZMS) turbulence is used as a guide.
