Steady shock interactions in perfect gas flows over double-wedge geometries are studied using computational fluid dynamics. In inviscid flow, four possible steady shock interactions are observed. These are the standard Type IV, V, and VI, as well as an apparent new interaction. In the Type IV and new interactions, a supersonic jet forms along the body surface. This jet produces oscillations in flow quantities on the surface. Preliminary laminar viscous calculations show that steady solutions exist for a range of Reynolds numbers and second wedge angles. These flows are very sensitive to the level of grid resolution, and it is only possible to correctly produce these interactions with very fine grids.
