Abstract
The study of nonequilibrium phenomena in air is of interest by itself due to the importance of these processes in such practical problems as supersonic flow past bodies in the Earth’s atmosphere, strong explosions, etc. The initial composition of air at room temperature is quite simple; its main components are molecular nitrogen and oxygen.* The composition of air behind the front of a strong shock wave is quite complicated. An increase in the temperature results in exciting internal degrees of molecular freedom, dissociation and ionization take place, nitrogen oxides are formed, etc. Before we consider nonequilibrium phenomena in a shock wave in air it is expedient to describe briefly the thermodynamic and optical properties of heated air which is at complete statistical equilibrium.KeywordsNitric OxideMach NumberShock FrontShock TubeVibrational EnergyThese keywords were added by machine and not by the authors.
