| Popis: | Our analysis of the burning of nitramine propellant in a turbulent shear flow involves several preparatory considerations, their development, and subsequent implementation. Involved are the thermochemistry and chemical kinetics of nitramine combustion, a flow model, and a turbulence model. Li and Williams (1996) provide a reduced mechanism for nitramine combustion, one appropriate for incorporation in a turbulent flow analysis. Our fluid mechanical model consists of simple shear flow with a specified thickness and a specified velocity and turbulent intensity in its external stream. The chemical composition of this external stream consists of the complete first stageof the combustion of nitramine. Given the overall complexity of the system, we adopt the model of turbulence rather than a more complete Reynolds stress model. A key parameter in the equations resulting from these considerations is a Reynolds number based on conditions in the external stream and on the shear layer thickness. We exploit ... |
