Abstract
AbstractIn supersonic and hypersonic flight double wedge geometries can cause very complex interaction phenomena between different wave types. These interactions can sometimes lead to anomalously high pressure and heat loads on the contour of aerospace planes like the ELAC1 configuration developed in the Collaborative Research Center (SFB 253) in Aachen. For the numerical simulation of such flows one has to use a method that should be both robust and accurate. The algorithm used here is based on the DLR FLOWer‐Code extended by several Upwind‐Splitting Methods for the physically correct description of the inviscid flux vector. Numerical solutions of 2 D inviscid shock interactions on double‐wedge geometries are presented and compared with corresponding results of other authors.
