| Abstract: | The nonlinear problem of the supercritical regime of interaction between sub- and supersonic inviscid jets flowing in a two-dimensional channel is investigated. The propagation of small pressure perturbations is considered. A numerical calculation is made of the shape of the streamline which separates the two jets, whose nonlinear perturbations have an oscillatory nature. The dependence is obtained of the amplitude of the oscillations on the similarity parameter representing the integrated characteristic of the profile of the unperturbed flow.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 5, pp. 156–160, September–October, 1985. |
