Multiburst and Fratricide Effects. Task 1: Numberical Methods and Computational Results

Abstract

This report documents and summarizes several developments in the field of numerical analysis of systems of hyperbolic conservation laws (especially, gas dynamics) and their viscous extensions (especially, the Navier Stokes equations); applications of the methods obtained in larger scale scientific computing with the objective of modeling complex physical phenomena, including careful checks against experimental data; and further applications of the methodology in the modeling of blast wave environments. Of special note are results concerning shear layer and boundary layer phenomenology (the latter including the effects of dust, preheating, etc.) and new methods for multimaterial calculations and problems involving wave speed stiffness (e.g., the early stages of fireball rise).
