The outflow of a gas jet from a supersonic nozzle
The appearance of shocks has been theoretically proved during the outflow of a stream from supersonic nozzles. Based on the hypothesis of liquid phase discretization, the bivariate model of the stream flowing away from a nozzle has been surveyed. The expressions for a flow rate at each point, its density, temperature and pressure are theoretically obtained. The calculations connected with the obtained formulas have shown good coincidence with literary experimental data on the outflow of the airflow from a supersonic nozzle. The theoretically calculated form of the stream coincides well with the experiment, where the process of the supersonic outflow is captured in photos.
