Studies on Low-Temperature Chemistry, Flames and Detonations in Hydrocarbon Combustion

Abstract

A comprehensive program is proposed to theoretically, computationally and experimentally study various issues related to the reaction mechanisms and the structure and propagation of laminar flames and detonations that are affected by the low-temperature chemistry(LTC) of hydrocarbon fuels. The program would include: (1) the development of reaction mechanisms governing the first ignition delay of the LTC, as well as comprehensive mechanisms covering low- to high-temperature chemistries identified through computational matched asymptotics; (2) an extensive suite of fundamental flame phenomena including laminar flame speeds, ignition and flammability limits, name stretch and preferential diffusion, and flame-front instabilities; and (3) the initiation and double-cellular structure of detonations. Results are expected to contribute usefully to the description of the combustion chemistry as well as the foundations of flames and detonation waves, for hydrocarbon fuels affected by the LTC.
