Zhukovskii Central Aerohydrodynamic Institute, 1 Zhukovskii Str., 140180, Zhukovskii, Moscow Region, Russia aut Influence of the External Force on the Vortex-Source Combination Crisis [Elektronische Daten] [A. Kucherov] This paper considers the force stagnation of a supersonic vortex-source combination flowing out into a vacuum, leading to a decrease in the radial Mach number to unity and stationary flow choking. The similarity parameters influencing the crisis are analyzed. It has been shown that the ″force″ crisis (choking) is also possible for the vortexsink combination flowing out of a submerged space. The formulation of the thermal crisis problem is generalized to the case of a given external force per unit mass and in a unit volume. Comparison has been made between certain characteristics of the crisis due to the applied external force in the absence of power supply/removal and the characteristics of the crisis due to the heat input in the absence of external force. The investigation has been carried out from the viewpoint of the perfect gas model.
