Abstract

It was recently demonstrated that shock wave enhancement could be achieved when a shock propagates in a constant cross-section duct through pairs of air-helium layers having a continually decreasing width (Igra and Igra in Shock Waves 16(3):199-207). A parametric study was conducted aimed at finding a two-layered, light-heavy gas arrangement that yields maximal shock enhancement; the heavy and the light gases used were air and helium, respectively. Effects associated with changes in following parameters were investigated: the number of alternating heavy/light gas layers, the applied reduction ratio between successive layers thickness, and the initial shock wave Mach number.
