Gas dynamic model of the expansion of a supercritical carbon dioxide pulse jet: A self-similar solution

The unsteady-state isentropic expansion of an initially homogeneous spherical cloud of a van der Waals gas into a vacuum is considered as a dynamic part of the problem of modeling a real gas pulse jet. A self-similar solution of the gas dynamic equations is obtained. The parameters of the pulse jet (density and temperature) that simulate the conditions of a real experiment are calculated.
