Old research pages

I'm keeping these old research pages here for the benefit of anyone who might arrive here from an external page. They are no longer updated. Please visit my new web site at http://sipapu.astro.illinois.edu/~ricker/. Eventually some content from these pages will migrate to the new site.

Sedov explosion problem

The Sedov explosion problem (Sedov 1959) involves the self-similar evolution of a cylindrical or spherical blast wave from a delta-function initial pressure perturbation in an otherwise homogeneous medium.

Physics
Hydrodynamics. Gamma-law equation of state.

Geometries
1D spherical; 1/2/3D Cartesian.

Parameters
p_ambient = 1E-5; rho_ambient = 1; exp_energy = 1; gamma = 1.4
