Web1 Dec 2016 · A shock Mach number M a = 2.50 reveals a particular phenomenon. The bubble gas ignites simultaneously at two spots, leading to two detonation waves that … The abruptness of change in the features of the medium, that characterize shock waves, can be viewed as a phase transition: the pressure-time diagram of a supersonic object propagating shows how the transition induced by a shock wave is analogous to a dynamic phase transition. When an object (or disturbance) moves faster than the information can propag…
