This communication presents efficient skeletal core combustion mechanisms for small C-0-C-4 fuel molecules using NUIGMech1.1. The skeletal mechanisms have been validated and can be utilized in the development of a five-component skeletal mechanism for real gasoline.
Core combustion kinetic mechanisms for small C-0-C-4 fuel molecules are not only of the utmost importance in understanding their individual combustion properties but are also the foundation for the development of kinetic models of real fuels. This brief communication intends to develop efficient skeletal core combustion mechanisms for the oxidation of C-0-C-3/C-4 fuels using the recently developed NUIGMech1.1 as the detailed mechanism. A combination of different skeletal mechanism reduction methods is employed to produce two skeletal mechanisms for C-0-C-3 and C-0-C-4 fuels, separately. The skeletal mechanisms have been validated by comparing against a wide range of combustion targets, and the maximum error in ignition delay time predictions is less than 10% for all of the targeted fuels. The C-0-C-3 skeletal mechanism is also employed as the core mechanism in the development of a five-component skeletal mechanism for real gasoline. The developed skeletal mechanisms should represent a valuable resource for mechanism development and kinetic modeling within the combustion community.
