本文综述了近年来湍流燃烧的研究进展，重点介绍了湍流燃烧的直接数值模拟（DNS）、大涡模拟（LES）和激光诊断。在湍流燃烧的DNS研究中，往往包括详细的动力学机制来研究湍流/火焰的相互作用。湍流燃烧的LES可分为火焰跟踪法、PDF法和火焰增厚法，在不久的将来将在许多燃烧器的工程应用中发挥重要作用。在湍流燃烧的激光诊断中，利用平面激光诱导荧光（PLIF）同时测量几种自由基浓度和粒子图像测速（PIV）同时测量多组分速度是研究湍流中局部火焰结构的有效方法。同时时间分辨的PLIF和PIV在未来的湍流燃烧研究中具有重要意义。
Recent progresses in turbulent combustion researches are summarized in this paper with a focus on direct numerical simulation (DNS), large eddy simulation (LES) and laser diagnostics of turbulent combustion. In DNS studies of turbulent combustion, detailed kinetic mechanism tends to be included to investigate turbulence/flame interactions. LES of turbulent combustion can be classified into flame tracking method, PDF method and flame thickened method, and will play important roles in the developments of many combustors in engineering applications in near future. In the laser diagnostics of turbulent combustion, simultaneous measurements of several radical concentrations by planer laser induced fluorescence (PLIF) and multi-components velocity measurement by particle image velocimetry (PIV) are effective to investigate the local flame structure in turbulence. The simultaneous time-resolved PLIF and PIV will have great importance in future researches on turbulent combustion.
