Instantaneous Point Explosion in Incompressible Fluid-like Media

Abstract

This report covers different issues relating to point explosion in incompressible fluid-like media. Suggested analysis takes into account 1) a finite size of the domain of the instantaneous explosion and 2) a finite size of the liquid media. The solutions in those cases cease to be self-similar but still can be reduced to the analysis of a single ordinary differential equation. The equation is rather complex, and the usage of computer-based numerical analysis is required. Fortunately, in the asymptotic case of unbounded fluid, the equation permits exact solution, which is not self-similar.
