摘要
本文针对湍流燃烧中模拟包括污染物生成的详细有限反应动力学的要求，用二阶矩封闭与简化概率密度的概念相结合的方法，提出了湍流燃烧的新二阶矩模型。此模型可兼顾适用于工程问题中的合理性和经济性。
To better simulate hydrocarbon, CO combustion and pollutant formation in turbulentreacting flows, a new second-order moment model of turbulent gas combustion is developedbased on the combination of a second-order moment closure with the concept of a simplified PDF. The proposed model can properly simulate the turbulence-chemistry interaction with finite-rate detailed kinetics, and computationally is acceptable for predicting complexengineering turbulent reacting flows.
