Structure and brightness of nonstationary supercritical shock waves in low-density air
Abstract
The propagation of nonstationary supercritical shock waves in low-density air is examined theoretically. An intermediate quasi-stationary stage of the propagation of high-intensity strongly radiating shock waves is identified where plasma behind the shock wave front has become nontransparent but the waves are still far from being stationary. In a rarefied plasma, this stage may last for a relatively long time. At this stage, the temperature ahead of the supercritical wave is much lower than that predicted by classical theory. Possible applications of the results are briefly discussed.
