Adaptive Multiresolution Methods for the Simulation of Shocks/Shear Layer Interaction in Confined Flows

Abstract

The main objective of this work is to study the ability of a multiresolution method based on wavelet approximation to predict unsteady shocked flows. A correct prediction of shock wave phenomena is often crucial in flow simulations for many industrial configurations such as in air intakes of supersonic vehicles or shock tube facilities where moving shock waves interact with shear layers. To capture these very fine and localized structures, many shock capturing schemes have been developed in the last decades that work with adequat robustness. However, shock wave/shear layer interactions generate unsteady vortical flows with separation that need adaptive multiresolution technics to achieve correct predictions.
