Analysis of H2/CO Reaction Mechanisms for the Performance prediction of Advanced Propulsion Systems

In High speed propulsion systems such as Dual Combustion Ramjet (DCR) engine and Regeneratively cooled engines, the combustion of syngas is very critical in the prediction of the propulsion systems. Utilization of the fuel for the combustion applications needs a comprehensive understanding of the reaction taking place to accurately predict the propulsive performance of the device. Also, the reaction steps of H2/CO forms the elementary reaction step for many hydrocarbon fuels such as RP-1, methane, etc and this makes the analysis of reaction mechanisms vital for the selection of an appropriate model for the numerical study of propulsive devices. In this study, performance of various reaction model were compared and found that USC model is best suited for wide range of operating conditions.
