NEW SELF-SIMILAR SOLUTIONS FOR THE UNSTEADY ONE-DIMENSIONAL EXPANSION OF A GAS INTO A VACUUM
New simple self-similar solutions for the unsteady expansion of a gas into a vacuum are found. They describe supersonic rarefaction in cylindrical and spherical symmetry for an arbitrary adiabatic index. An inner boundary exists at a constant self-similar coordinate. In the asymptotic region a universal isothermal density law is given which depends only on geometry. Important applications lie in the field of laser generated plasmas.
