Investigation of nonequlibrium radiation and relaxation phenomena in shock tubes
The paper presents the experimental results for the excited time of the nonequlibrium radiation and the ionization behind strong shock waves. Using a optical multichannel analyzer, InSb infrared detectors and near-free-molecular Langmuir probes, the infrared radiation, the electron density of air and the nonequlibrium radiation spectra at different moments of relaxation process in nitrogen test gas behind normal shock waves were obtained, respectively, in hydrogen oxygen combustion driven shock tubes.
