ASYMPTOTIC SOLUTIONS FOR THE EXPANSION OF GAS INTO VACUUM

Abstract

When a spherical or cylindrical gas cloud expands into vacuum, the resultant flow becomes asymptotically self-similar and independent of the original cloud diameter. An analytic solution for the asymptotic density profiles, is re-examined and a new solution proposed, which gives better agreement with numerical computations. Some applications of the asymptotic solutions are discussed.
