| Abstract: | The effect of swirling the flow at the nozzle inlet on the shape of the optimum supersonic section with a break at the point of intersection of the limiting characteristic and the contour is investigated within the framework of the ideal (inviscid and non-heat-conducting) gas model. A direct method based on reduction to a problem of nonlinear programming is used for the numerical solution of the corresponding variational problem.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 3, pp. 155–160, May–June, 1989.In conclusion, the authors wish to thank N. I. Tillyaeva and A. N. Kraiko for participating in the discussions and A. A. Glazunov for assisting with the work. |
