Influence of the initial particle velocity on the transient axisymmetric motion of the gas
Abstract
The paper presents a numerical analysis of flows generated by a sudden increase in pressure within a cylindrical volume, with the result that an initial velocity is imparted to the particles. It is shown that in such flows there forms a secondary discontinuity which propagated from the symmetry axis behind the bow shock wave. There also exists a prolonged time interval during which the distribution of the gas parameters in the region between two fronts may be approximated by a similar solution of the Euler equations, which corresponds to a sink of variable intensity.
