An unsteady shock wave (travelling Mach = 2.85) impacts a pyramid obstacle. A first reflexion occurs and then the shock is diffracted by the expansion from the spike of this pyramid. The 90 degrees corner trigger a separation.
Computed with Typhon open source solver (http://typhon.sf.net) with a 600k quad mesh. Inviscid computation. HLLC and MUSCL methods used. Flood and contours of temperature.
