Highly scalable multiphysics computational framework for propulsive energetic systems

Abstract

A computational framework to perform multiphase ow simulation is described and one of its application is focused on modelling of solid-propellant rocket motors. This framework allows to compute the chamber dynamics of the gas mixture, investigate the evolution of Al Lagrangian burning droplets and understand the generation of alumina smoke. Unstructured grids are used to enable meshing of geometrically complex configurations. An efficient parallel droplet-localization algorithm has been developed for unstructured mixed meshes. © 2009 Springer-Verlag Berlin Heidelberg.
