AASERT95/Science and Engineering Training in Combustion and Propulsion

Abstract

AASERT support permitted an additional graduate student to be added to AFOSR's "Fuels Combustion Research" program at Princeton. This support allowed fuel pyrolysis and combustion to be studied under both sub and supercritical conditions. This newly integrated program, with AASERT support, proved to be an enormous success. It was found that under supercritical conditions the pyrolysis rate of fuels have a pre-exponential rate A factor order of magnitudes greater than results obtained at 1 atm. The activation energies of the complete energy range tested remained the same. Further, due to the phenomenon known as "caging" for the fuels studied, cyclic hydrocarbons formed under supercritical conditions, but not at 1 atm, and these cyclic hydrocarbons led to polynuclear aromatics (PAH) that are the precursors to particulate formation.
