Conversion of a Cylindrically Confined Surface Explosion into a One-Dimensional Blast Wave.

Abstract

The NRL Flux-Corrected Transport Code FAST2D is used to model the conversion of a cylindrically confined surface explosion into a one-dimensional blast wave. The ideal gasdynamic equations are used, together with a real-air equation of state, to follow the development of an explosion initialized with the 1-kton standards as it reflects from the cylindrical boundary and propagates upward. Multiple shocks develop and the solution quickly (in 1-2 reflection times) approaches the one-dimensional asymptotic state described by the Taylor-Sedov similarity solution. (Author)
