Simulation of Complex Shock Reflections from Wedges in Inert and Reactive Gaseous Mixtures

Abstract:

The Flux-Corrected Transport FCT technique for solving fluid equations reduces numerical diffusion, permitting calculations with Reynolds numbers considerably in excess of the cell Reynolds number. Recent advances in FCT, including a multidimensional flux limiter and a dynamic adaptive rezone, are illustrated in the problem of transient reflections of planar shocks from wedges in inert and reactive media. Results are obtained with high resolution which are in quantitative agreement with experiments.
