Abstract

The presence of a second phase in a gas jet flowing out of a nozzle leads to considerable changes in the flow pattern [1–3]. Thus, as the particle concentration increases, the central jump in compression [shock wave] moves in the direction of the nozzle cutoff, while the Mach number on the axis of the jet in front of the forward jump diminishes. In this paper we shall consider the numerical solution of the problem of an axisymmetrical, two-phase, underexpanded jet flowing out of a straight nozzle into a submerged space. It is assumed that the distribution of the flow parameters is uniform over the jet cross section and that no thermal or dynamic retardation of the particles occurs.
