Abstract : Details of the propellant combustion zone microstructure were studied using the simpler configuration resulting from burning down the interface between contacting oxidizer and fuel slabs. Steady burning profiles and burning rates were determined experimentally for an ammonium perchlorate oxidizer and PMMA fuel. An iterative procedure was used to determine the heat source distribution in the gas phase that would produce the experimentally observed profiles and burning rates. The procedure involved solution of energy equations in the gas and solid, and the Navier-Stokes equations in the gas, and requiring that the experimentally-based boundary conditions in the solid and gas at the surface be suitably matched. The results indicate the approximate dimensions and location of the flame zone, and details of the thermal field. (Author)
