【Abstract】 As a promising renewable fuel, 2, 6, 10-trimethyl dodecane has received extensive attention. In order to deeply understand the combustion process of this fuel, its detailed chemical reaction mechanism is developed by using the reaction class method. The ignition delay time is verified using the detailed chemical reaction mechanism, and results show that the addition of new reaction paths can improve the prediction accuracy in the low-temperature region. At the same time, the concentration of important species in the flow reactor and the velocity of laminar flame propagation are also verified. The good agreement between simulated and experimental values proves the validity of the construction process of this chemical reaction mechanism, which creates an opportunity to study the reaction flow process of fuels by simulations as well.更多还原
