Effect of a gas-phase reaction on the combustion performance of a sandwich layered system

This paper considers a sandwich layered combustion model (an oxidizer and a fuel) that takes into account condensed- and gas-phase chemical reactions and transverse heat and mass transfer. Under particular simplifications, algebraic expressions are obtained for the burning rates of the components and the temperature and concentration of gaseous reagents on the burning surface. Calculated dependences of the burning rate on the sandwich size agree with experiments.
