Complex Multicomponent Surrogates for Commercial Kerosene-Type Aviation Fuels: Modeling Fuel Combustion Characteristics
摘要
A skeletal reaction mechanism is developed for the ignition and combustion of complex dodecane/decane/isooctane/isocetane/toluene surrogates for kerosene-type aviation fuel. The mechanism incorporates submechanisms for the oxidation of dodecane, decane, isooctane, isocetane, and toluene in the high-temperature and low-temperature regions, as well as in the negative temperature coefficient zone. The mechanism is validated against experimental data on ignition delay times, laminar flame speeds, and species concentration profiles. The combustion characteristics of the surrogates are evaluated using the developed reaction mechanism. A demonstration computational fluid dynamics simulation of the operating process in a low-emissions gas turbine engine combustor utilizing rich-lean combustion technology is also performed.
