Solution to the self-similar problem of gas flow into a vacuum in a two-temperature hydrodynamic approximation
Abstract
The paper investigates the two-dimensional problem of the dispersion into a vacuum of a gas formed as a result of the interaction of radiation with matter. The gas is assumed to be completely ionized and is considered in a two-temperature hydrodynamic approximation with allowance for electron heat conduction and energy exchange between ions and electrons. Qualitative analysis and construction of self-similar solutions by a numerical method are carried out for the case of an infinitely large absorption coefficient. The properties of various regimes of heat propagation in a moving medium are studied.
