Abstract
A skeletal reaction mechanism for the ignition and combustion of complex dodecane/decane/isooctane/isocetane/toluene surrogates of kerosene-type aviation fuels has been developed. The mechanism includes submechanisms for the oxidation of dodecane, decane, isooctane, isocetane, and toluene in the high- and low-temperature regions, as well as in the inverse temperature coefficient zone. The mechanism was tested using experimental data on ignition delay time, normal flame propagation velocity, and component concentration distribution. The combustion characteristics of the surrogates were tested using the developed reaction mechanism, and a demonstration CFD simulation of the operating process in a low-emission combustor of a gas turbine engine using rich-lean combustion technology was conducted.
