Abstract

The kinetics of NO and NO2 of behind shock fronts propagating in air are analyzed. It is shown that in certain cases it is necessary to use fairly detailed chemical reaction schemes involving not only N2, O2, NO, N, and O, but also NO2, N2O, H2, OH, and H and to take into account the mutual effects of vibrational relaxation and chemical transformations. It is established that neglecting the chemical processes involving NO2 only can lead to significant errors in the length of the relaxation zone (up to 25 times), the gasdynamic parameters (up to 20%), and the NO concentration (up to 3 times).
