This is a cooperative agreement awarded by the National Aeronautics and Space Administration (NASA) to The Leland Stanford Junior University, commonly known as Stanford University, with a ceiling value of $1,000,000.00. The objectives of this contract are to develop and validate chemical kinetics models capable of predicting the influence of jet fuel composition on critical phenomena related to aircraft engine lean blow out, cold start, high altitude relight, and the production of nitrogen oxides (NOx) and soot. The work will closely coordinate with experimental activities of the Federal Aviation Administration's National Jet Fuels Combustion Program and related NASA projects. The resulting chemical kinetic models will be delivered to various collaborators, including researchers at the University of Connecticut and General Electric, for further model reduction, implementation, and testing. This contract does not have a set-aside designation, reflecting Stanford's status as a large, established research institution competing for federal work on full and open terms.

The objectives of the proposed study are to develop and validate chemical kinetics models capable of predicting the influence of jet fuel composition on chemical phenomena critical to aircraft engine lean blow out, cold start and high altitude relight, and the production of NOX and soot from aircraft engine combustors. The proposed study will have a close coordination with experimental activities of the FAA national jet fuels combustion program, njfcp and related NASA projects of the current NRA. Model development and validation will rely heavily on multi species time histories of ethylene, methane and other key species in jet fuel pyrolysis in shock tube and flow reactors, and ignition delay time and multispecies time histories of fuel oxidation in shock tubes and species profile in the flow reactor. Collaborative activities include, the delivery of the chemical kinetic models to a a professor of uconn for model reduction; and the delivery of reduced models for jet fuel combustion to various FAA njfcp teams for implementation and testing. Also, the combined fuel combustion, and soot and NOX formation model will also be delivered to NASA and, among others, a professor of GE for further test and validation.
