A shock wave is a type of propagating disturbance. When a wave moves faster than the speed of sound in a liquid, gas or plasma (a fluid, in physics terminology) it is a shock wave.
This was theorized to be due to bifurcation of. the reï¬ected shock wave associated with shock-wave boundary layer interaction. Previous researchers have observed shock wave bifurcation in experiments per-. taining to shock tube performance [5, 6, 7, 8, 9]. Shock bifurcation is the splitting of. a reï¬ected shock near the wall into an oblique and a normal wave due to interaction. with the ï¬uid in the boundary layer created by the incident shock. This results in a. foot extending from the wall to the primary reï¬ected shock as sketched in Fig.
