Abstract

Structures which are similar to double wedges usually exist in a supersonic inlet. When a supersonic flow goes through double wedges, oblique shock waves intersect and shock wave reflection appears. In an off design condition, Mach Reflection (MR), one kind of shock wave reflection, probably appears. The laser energy deposition helps decrease the Mach stem height and reduce the total pressure loss. Numerical simulation on the influence of deposition location and laser energy in reducing the Mach stem height was investigated in Mach 3.45, 5, 6, 7. Mach Reflection was achieved at different Mach number. The simulations and analysis showed that proper increase of distance between energy deposition location and Mach stem where was near by the upstream oblique shock waves would have a better effect on decreasing Mach stem height. When inflow Mach number changed, the influence of laser energy deposition became different at a variety of deposition location
