Development of Detailed and Reduced Kinetics Mechanisms for Surrogates of Petroleum-Derived and Synthetic Jet Fuels.

摘要

The oxidation and pyrolysis of a variety of fuels of relevance to air breathing propulsion were studied experimentally behind reflected shock waves, in flow reactors, as well as in laminar and turbulent flames. The measurements included ignition delays and species time evolutions in shock tubes, species profiles in flow reactors, and propagation speeds and ignition/extinction limits of laminar flames. Additionally, a facility was constructed that allows for the study of turbulent flames at very high Re numbers and fuels as heavy as n-dodecane. The main goal of the completed program was to identify the important kinetic pathways of jet fuel pyrolysis and oxidation under conditions that mimic those encountered in jet engines, and to develop appropriate models for real fuels based on the experimental data. This was a collaborative three-year research effort between the following universities and investigators: University of Southern California: F.N. Egolfopoulos (PI), H. Wang (co-PI); Drexel University: N.P. Cernansky (co-PI), D.L. Miller (co-PI); Princeton University: C.K. Law (co-PI); Stanford University: C.T. Bowman (co-PI), R.K. Hanson (co-PI), H. Wang (co-PI).
