THE STABILITY OF SPHERICAL BLAST WAVES,
Abstract
The stability of strong spherical blast waves to infinitesimal perturbations is examined in the limit (gamma-1) << 1, where gamma is the ratio of specific heats. By making a 'thin sheet' approximation to the geometry it is found possible to describe all perturbations as a sum of spherical harmonics. By transforming to a new time-like variable, one can obtain a set of ordinary constant-coefficient differential equations for the perturbation corresponding to each spherical harmonic, and one then obtains a dispersion relation giving the growth rate of each harmonic.
