Abstract
Results of an investigation into the diffusion processes in a jet of low density behind a strongly underexpanded sonic nozzle, in the zone of mixing with the surrounding gas, are presented. By means of electron-beam methods, the structure of the jet was studied in the case of expanding N2, into an atmosphere of CO2 + N2 in transient regimes of flow varying from solid to rarefied. The results of an analysis of the fields of concentration of the separate components are given in a generalized form.
