Gas Dynamic Model of Expansion of the Pulse Jet of Supercritical Carbon Dioxide. Self-Similar Solution

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

Key words: supercritical carbon dioxide, pulse supersonic jet, van der Waals gas, isentropic expansion
