A new version of the residual-based scheme has been developping for computing compressible ow on unstructured grids. The third-order and forth-order of this scheme will be tested by the pure advection case and several cases governing by the Euler equations. Then this new version is compared with the classical upwind schemes such as Roe scheme.
This work is devoted to exploring a new procedure to develop subgrid-scale (SGS) models in the context of large-eddy simulation (LES) of a passive scalar. Starting from the Noll’s formula (Noll 1967), the concept of an optimal estimator is first used to determine an accurate set of parameters to derive a SGS model. The SGS model is then defined as a(More)
