Laminar Flame Speeds of Dilute Triethyl Phosphate in H 2- and CH 4-Air Mixtures

2017 by Travis Sikes, Nicholas Niemiec, Waruna Kulatilaka, Eric Petersen. Laminar flame speed measurements were performed in mixtures of triethyl phosphate (TEP) with a parent fuel at 120 C and 1 atm. The parent fuels, hydrogen and methane, were chosen as baseline fuels because each of these compounds has been the subject of extensive research. Results showed an overall 43% decrease in flame speed for the TEP/methane/air mixture and a 30% decrease for the TEP/hydrogen/air mixture relative to their neat counterparts. The Markstein curves of both parent fuels look similar with the introduction of TEP when compared to the cases without TEP. These results will serve as global benchmarks to improve an existing but unrefined chemical kinetics submechanism. This submechanism will in turn be used to create safe and effective countermeasures for sarin destruction in a variety of conditions beyond what could safely be investigated in controlled laboratory studies.
