Abstract:This paper studies the computation of stress tensors for turbulent compressible flow for purposes of subgrid modeling for LES (large eddy simulation) methods in an effort to provide a model closure. The method uses and compares a variety of filters and special decomposition methods on the velocity field and the density. The studies are done over a range of Mach numbers. The subgrid models for the velocity range from Smagorinsky type models to Leray-models, while approximate deconvolution methods are used for the density. Problems such as shocks in a developing turbulent flow are left for future research.
