ANALYSIS OF SUBGRID SCALES AND SUBGRID SCALE MODELING FOR SHOCK-BOUNDARY-LAYER INTERACTION

Аннотация

An alternative approach to large-eddy simulation based on approximate deconvolution (ADM) is compared with standard subgrid scale models by a priori tests for supersonic compression ramp flow. With ADM an approximation of the non-filtered field is obtained by truncated series expansion of the inverse filter operator. Scale-similarity model and ADM give the best correlation of subgrid scale terms with filtered DNS data. Lower correlations are obtained with the dynamic mixed model, the dynamic Smagorinsky model, and the standard Smagorinsky model. It is also found that explicit compressible subgrid scale contributions cannot be neglected and require modeling.
