Comprehensive Chemical Kinetic Model of 2,6,10-Trimethyl Dodecane

As
a novel alternative fuel and surrogate component, 2,6,10-trimethyl
dodecane has received extensive attention. For designing and optimizing
internal combustion engines and propulsion systems by computational
fluid dynamics, and providing more choices for a branched surrogate
component to develop a more accurate surrogate model, a comprehensive
detailed chemical kinetic model for 2,6,10-trimethyl dodecane has
been developed based on 35 reaction classes to numerically describe
its experimental observations. The proposed detailed kinetic model
for 2,6,10-trimethyl dodecane has been validated against a wide range
of experimental data, including ignition delay time, flow reactor,
and laminar flame speeds. A good agreement between the numerical and
the experimental data is observed. Using the kinetic model reduction
scheme, high-temperature and low-temperature chemical kinetic models
were eventually obtained and validated against the detailed kinetic
model. The successful implementation of a kinetic model construction
based on 35 reaction classes has indicated the possibility of its
application for the development of mechanisms for the larger hydrocarbon
fuels with asymmetric and iso-paraffinic molecular structures.
