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.
