The turbulent flame is used in a wide variety of applications. However, combustion is an extremely complex phenomenon combining a lot of physical, chemical processes and enough elucidation is not yet done. In order to predict accurately the NOx emission of turbulent, we developed the combination method based on "the extended flamelet model". In this method, the detailed kinetics calculation is separated from the turbulent flow calculation, and then they are recombined in terms of recombination parameters. On the other hand, the instrumentation technology which had accumulated up to now was adopted to cope with the problems of taking a picture to the fast process and the resolution on the image processing in the experiment.Following researches were done based on such techniques.1)Survey on the method using the turbulent flow model and the turbulent combustion model2)Improvement of the combination method and execution of the numerical calculation for the unsteady counterflow diffusion flame3)Establishment of the measurement system with the high speed and the high-resolution4)Execution of the experiment using OH-PLIF and acetone-PLIF for verification of the combination method5)Execution of the numerical calculation using DNS and comparison with the experiment

湍流火焰的应用范围很广。然而，燃烧是一种极其复杂的现象，它结合了许多物理、化学过程，目前还没有得到足够的阐明。为了准确预测湍流中NOx的排放，我们发展了基于“扩展火焰面模型”的组合方法。在该方法中，将详细的动力学计算与湍流计算分开，然后根据复合参数进行复合。在此基础上进行了以下研究：1)对湍流模型和湍流燃烧模型的组合方法进行了综述；2)改进了组合方法，进行了非定常逆流扩散火焰的数值计算；3)建立了高速、高分辨率的测量系统；4)用OH-PLIF和丙酮-PLIF对组合方法进行了实验验证；5)进行了数值计算，并与实验结果进行了比较
