Abstract: This paper presents the results of mathematical modeling and numerical solution of the evolution of the cavity at the border rocket launch. Relevance of detailed mathematical modeling of the evolution of the boundary of the cavity due to the fact that there is a need to identify significant largest unsteady forces and moments acting on the torpedo. The evolution of the gas cavity which is explored in this paper associated with the processes of emergence, changes in the shape and volume of the cavity at the end of the annular gas jet into a liquid when starting a torpedo from the media. In this case, the essential features of the geometry of the carrier and make his move in the water, the shape of the annular gap and the mass flow of gas flowing out of the annular gap. As a result of numerical results were obtained in good agreement with experimental data.
Keywords: mathematical modelling, numerical solution, cavity, gas, liquid.
