Potential Energy Surfaces, Reaction Kinetics, and Transport Processes in High-Speed Combustion

Abstract

The main goal of the completed research program was to provide critical insight into the physico-chemical processes that control turbulent flame propagation under conditions of relevance to air-breathing propulsion. During the reporting period, the following tasks were completed: (1) Concept testing of a potentially new kinetic modeling approach based on global Gibbs potential energy landscape; (2) Modeling studies of heavy fuel decomposition effects on fundamental flame properties; (3) Development of a near-term solution to real-fuel kinetic modeling on the basis of the above concept; (4) Continued development of foundational fuel chemistry model using the method of uncertainty minimization by polynomial expansion; (5) Development of a piloted premixed jet flame that could be sustained for very high Reynolds numbers and for fuels ranging from hydrogen to JP-8; (6) Validation of the new turbulent flame facility through experimental studies of extinction of turbulent stagnation flames for a wide range of fuels; (7) Experimental studies of the global and detailed structure of turbulent jet flames for a wide range of fuels.
