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.
