Abstract:
A numerical model of generation of the nonequilibrium molecular radiation in a vacuum ultraviolet spectral region (VUV radiation with a wavelength shorter than 200 nm) behind a shock wave in air in a range of varying its velocity of 4.5–9.5 km/s is developed. This numerical model is verified using the results of experiments in a shock tube for studying the photoionization effect before the shock-wave front in a wave-length range of 85–105 nm. Some features of nonequilibrium VUV radiation, particularly its generation a very thin high-temperature layer behind the shock-wave front, are established.
