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

湍流火焰有着广泛的应用。然而，燃烧是一种极其复杂的现象，结合了许多物理、化学过程，目前尚未有足够的阐明。为了准确预测湍流NOx排放，我们提出了基于“扩展火焰模型”的组合方法。该方法将详细的动力学计算与湍流计算分开，然后根据重组参数将它们重新组合。另一方面，采用目前积累的仪器技术来解决实验中拍照的快速处理和图像处理的分辨率问题。基于这些技术进行了以下研究。 )湍流模型和湍流燃烧模型方法的探讨2)非定常逆流扩散火焰组合方法的改进和数值计算的执行3)测量系统的建立高速和高分辨率4)使用OH-PLIF和丙酮-PLIF进行实验以验证组合方法5)使用DNS进行数值计算并与实验进行比较
