The study focuses on numerical analysis of the flow structure in the rocket engine chamber of solid propellant with a recessed nozzle when self-induced pressure oscillations occur. Findings of the research show that the flow structure essentially depends on the shape of the flow part of the combustion chamber and is characterized by the formation of intense toroidal vortices. We propose a method for estimating the probability of occurrence of such vortices and their effect on the intensity of pressure pulsations in the combustion chamber.
