The density (top left), velocity (top right), and pressure (bottom left) profiles for a wind-driven explosion (m = 2; left) in a constant-density (n = 0) ambient medium and γ = 5/3. The black dashed curves give the predictions from the self-similar solution, while the orange curves are from a FLASH hydrodynamical simulation. The bottom right panel shows the RS shell width, Δr, as a function of the radius of the CD, both from FLASH (orange) and as predicted by the self-similar solution (black dashed).
