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 kinetic modeling has become more and more important in the analysis of combustion systems. Considerable progress has been made in the development of combustion models in recent years. This review includes the following contents: electronic structure methods for combustion kinetics, recent developments on the calculation methods of thermodynamic parameters and rate constants in combustion, developments of combustion mechanisms and reduction techniques, molecular simulations with reactive force fields, combustion intermediate measurements, experiments for ignition delay time with shock wave tubes and combustion diagnostics. Due to the extreme complexity of reaction networks, the combustion mechanism is still not clearly understood by researchers. Owing to the strong application background, the combustion kinetics have attracted attention in recent years. The solver for reaction rate of intermediate species during combustion occupies the central point in combustion simulation. The progress in the research on reaction-turbulence interactions, and the combination of combustion kinetics with computational fluid dynamics, will facilitate fuel design and combustion simulation. To build a reliable combustion model for achieving a reasonable flow field structure description of engines is another important aspect.

Key words: Hydrocarbons, Combustion reaction, Pressure-dependency, Combustion mechanism, Combustion diagnostics
