Volterra integral equation method in the study of dynamics of self-gravitating gas bounded by free surface

Abstract: The paper investigates dynamics of the finite mass of self-gravitating ideal gas with a variable flow bounded by free surface. Unsteady gas flows are described by a phenomenological mathematical model of gas dynamics, which is constructed using a system of nonlinear integral-differential equations written in Eulerian coordinates. The gas motion is considered under the condition that the free boundary at all times consists of the same particles. This circumstance makes it convenient to switch from Eulerian coor… Show more
