An exact analytical solution in radiation gas dynamics

The Brinkley-Kirkwood theory, as modified by Bhatnagar and Kushwaha for the inclusion of radiation pressure, is applied to obtain an exact analytical solution for radiation pressure, shock velocity, etc., when a strong explosion takes place in a cold undisturbed gas obeying an exponential density distribution. Cases involving spherical symmetry, axial symmetry or spheroidal symmetry are also considered.
