The Sedov self-similar point blast solutions in nonuniform media
Abstract
The character of a spherical blast wave propagating radially outward in a pressureless medium with density decreasing as τ -ω changes dramatically as ω and the adiabatic index γ vary. Plots of the Sedov formulas for the density, velocity, and pressure profiles behind the shock front for a selection of different parameters illustrate this and suggest that some of the solutions satisfy the conditions for the Rayleigh-Taylor or convective instablity.
