Aerodynamic objects with a slender fore-body and blunt aft-body configuration traveling at supersonic speeds can generate large-amplitude shock wave oscillations. This visually stunning phenomenon is caused by the interaction between shock waves and separated flow over the fore-body. This set of eight false-colored schlieren snapshots were experimentally obtained in a Mach 6 flow over an axisymmetric spike-cylinder over one oscillation time period T, which in this case corresponds to about 470 microseconds.
