【摘要】：化学反应动力学是燃烧过程分析的重要工具。燃烧微观反应过程、复杂反应机理、燃烧实验测量和湍流燃烧数值模拟等方面的研究工作已经取得了长足进步。本文主要介绍燃烧反应动力学研究方法,包括电子结构方法、燃烧反应热力学和速率常数的计算方法、燃烧详细机理构建和简化、反应力场分子模拟以及燃烧中间体测量、燃料点火延迟和光谱诊断等方面的研究现状。燃烧反应动力学具有很强的应用背景,燃烧过程化学物种的反应速率计算是湍流燃烧数值模拟的一个中心任务。由于燃烧反应网络的高度复杂性,我们对燃烧机理的认识还远不清楚。化学反应和湍流相互作用研究的深入、燃烧反应动力学和计算流体力学的协同发展,将对新燃料设计、燃烧数值模拟、发动机内流道流场结构的准确描述产生深远影响。
[Abstract]:Chemical reaction kinetics is an important tool for combustion process analysis. Great progress has been made in the research of combustion microscopic reaction process, complex reaction mechanism, combustion experimental measurement and turbulent combustion numerical simulation. In this paper, the research methods of combustion reaction kinetics are introduced, including the electronic structure method, the calculation method of combustion reaction thermodynamics and rate constant, the construction and simplification of combustion detailed mechanism, the molecular simulation of reaction force field and the measurement of combustion intermediates. Research status of fuel ignition delay and spectral diagnosis. Combustion reaction kinetics has a strong application background. The calculation of reaction rate of chemical species in combustion process is a central task in the numerical simulation of turbulent combustion. Because of the high complexity of combustion reaction network, our understanding of combustion mechanism is far from clear. The further study of the interaction between chemical reaction and turbulence and the coordinated development of combustion reaction kinetics and computational fluid dynamics will have a profound impact on the design of new fuel, the numerical simulation of combustion and the accurate description of the flow field structure in the inner flow channel of the engine.
