Abstract
In this paper, two acoustic problems of importance to the engineering community are solved using hybrid RANS-LES methods. More specifically, results from the problems of supersonic flow over a surface mounted protuberance and that of a supersonic jet impingement on a flat plat are presented. Through these studies, it is shown that hybrid RANS-LES methods are adequate at resolving the necessary frequency bandwidth relevant to these problems. Good agreement with available experimental results is obtained for both problems.
