Study on the Chemical Reaction Mechanism of Diesel-Natural Gas-Hydrogen Three Fuels
摘要: 本文为了探究RCCI三燃料(柴油–天然气–氢气)燃烧领域中,特定两组化学反应机理对于真实燃烧情况的预测合理性,对三燃料燃烧化学反应机理进行数值模拟研究,对比了不同机理对于正庚烷,天然气,氢气点火延迟时间和层流火焰速度的模拟结果,发现143-746机理在对正庚烷、氢气的层流火焰速度和对天然气、正庚烷的点火延迟时间方面的模拟效果更好,76-464机理在天然气层流火焰速度方面优于143-746机理,对氢气点火延迟时间的模拟方面二者与实验值的偏差程度类似,区别并不明显。综合考虑认为143-746机理更适合应用在RCCI三燃料燃烧的相关研究中。
Abstract: In order to explore the rationality of the prediction of the real combustion situation of specific two groups of chemical reaction mechanisms in the field of RCCI three-fuel (diesel-natural gas-hydrogen) combustion, this paper conducts numerical simulation research on the chemical reaction mecha-nism of three-fuel combustion, compares the simulation results of different mechanisms for n-heptane, natural gas and hydrogen ignition delay time and laminar flow flame velocity, and finds that the 143-746 mechanism has a better simulation effect in the laminar flow flame velocity of n-heptane and hydrogen and the ignition delay time of natural gas and n-heptane. The 76-464 mechanism is superior to the 143-746 mechanism in terms of natural gas laminar flow flame veloc-ity, and the simulation of hydrogen ignition delay time has a similar degree of deviation from the experimental value, and the difference is not obvious. Based on comprehensive consideration, it is believed that the mechanism of 143-746 is more suitable for the research of RCCI three-fuel com-bustion.
