Abstract

Recent experimental and numerical studies on Carbon Combustion Synthesis of Oxides (CCSO) have revealed that the gas transport behavior is rather complex with respect to traditional SHS systems. It involves at least two gaseous components: oxygen (oxygenator) as the main and practically unique gaseous reagent in gas-solid SHS reactions and carbon dioxide which is released in the post-combustion zone in CCSO. The goal of this study is to develop Two Gas Flow (2GF) model of filtration combustion counting resistance distribution in a porous reacting media and enabling the numerical investigation of the complex gas dynamic behavior during CCSO. In contrast to classical filtration combustion (FC) models, the proposed 2GF model for CCSO is capable of considering and predicting potential gas motion as well as complex vortex flows.
