NUCLEAR EXPLOSION INTERACTION STUDIES. VOLUME II. TWO-DIMENSIONAL CODE DEVELOPMENT

Abstract

The HECTIC code is a two-dimensional Eulerian radiative hydrodynamics code designed for nuclear and laser phenomenology applications involving primarily vapor-phase materials, with provisions for heat conduction and vaporization of condensed matter. In this report, a formulation is presented for an improved method of solving the hydrodynamic equations. Solution of the radiative transfer equations by the long-characteristic method is discussed, and computer codes utilizing this approach are presented. The short-characteristic method is also discussed. The nonequilibrium diffusion approximation in two dimensions is considered, and a study of algorithms for solving the implicit difference equations which arise is reported. Experimental codes utilizing the nonequilibrium diffusion and short-characteristic methods are presented.
