Development of Multipurpose Skeletal Core Combustion Chemical Kinetic Mechanisms

Core
combustion kinetic mechanisms for small C0–C4 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 C0–C3/C4 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 C0–C3 and C0–C4 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 C0–C3 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.
