Abstract
The problem of the optimization of the supersonic portion of a nozzle for gas flow in the case of certain nonequilibrium processes was solved in [1, 2]. The authors examined the flow scheme in which the closing Mach line of the first family arrives at the initial rarefaction wave fan. At the same time, in [3] in the solution of the analogous problem for the case of gas flow with foreign particles it was shown that it is advisable to consider also a different scheme, in which the closing characteristic arrives at the axis of symmetry outside the initial rarefaction wave fan. In the following we present results of a study of such a scheme for gas flow with nonequilibrium processes taking place. The necessary conditions which define the optimum contour are obtained and, in particular, the conditions which define the coordinate x and the magnitude of the angle at the corner points.
