The overall goal of the Combustion and Energetic Materials group is the development of a sub-grid combustion model (referred to as 'Rocfire') at a resolution of 1 to 10 microns that describes the detailed physics coupling the solid-phase to the gas-phase.

The sketch at the right shows the proposed three-dimensional combustion model.

Important questions to be addressed include, but are not limited to: (1) the gas-phase flame structure,(2) burning rate characteristics,(3) the generation of vorticity, (4) turbulence generation, and (5) the interaction with pressure and velocity fluctuations generated in the core flow.

The key ingredients of the combustion sub-grid model include, but are not limited to: (1) three-dimensional, (2) heterogeneous propellant, (3) non-planar regression of the surface, (4) complex condensed-phase kinetics, (5) unsteady heat conduction in the solid, (6) melt layer, (7) Al particles, (8) AP decomposition flame and binder-AP flame, (9) radiation, and (10) influence of chamber flow (shear, acoustics, turbulence, etc.)
