There are two types of shock reflections possible in supersonic wedge flows, namely Regular Reflection (RR) and Mach Reflection (MR). Which one appears depends on geometry and inflow conditions.The reflections can be described by shock polars and there exist certain parameter conditions where both solutions are possible. These conditions are often referred to as Dual‐Solution Domains and in previous investigations authors indicate that there hysteresis phenomena can be observed. Numerical results of steady wedge flows where such hysteresis phenomena appear are presented which have been achieved using the DLR FLOWer‐Code extended by several Upwind‐Splitting Methods for the physically correct description of the inviscid flux vector.
