Consistent Solutions of the Radiation Diffusion Equation in Spherical and Cylindrical Geometries
Ethan Smith, Evan Bursch, Ryan G. McClarren
We have extended the radiation diffusion model of Hammer and Rosen to diverging spherical and cylindrical geometries. The effect of curvilinear geometry on the supersonic, expandin…
