A sub-scale GOx/GCH4 rocket combustor has been simulated by different groups using various numerical methods. The current contribution focuses on the effects of chemistry and combustion modeling on the turbulent flame shape and structure, as well as the resulting axial pressure profile and wall heat flux, for which experimental data are available. Two different kinetic schemes have been used, combined with various models for turbulence and turbulence-combustion interaction (TCI). To evaluate the impact of combustion chemistry, the schemes are first studied on canonical laminar flames and evaluated against a detailed chemical scheme. The results obtained by the different groups on the target configuration demonstrate the strong impact of the models and the consequences for pressure and wall heat flux prediction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
