摘　　要：现有的湍流燃烧模型中,有的缺乏普适性,也有的用于大涡模拟的计算量太大.一种基于湍流流动模拟思路的统计矩方法被提出来,称为二阶矩(second-order moment,SOM)燃烧模型,用于非预混射流火焰和旋流火焰的雷诺平均模拟(Reynolds-averaged Navier-Stokes modeling,RANS)和大涡模拟(large-eddy simulation,LES),以及钝体后方预混火焰的大涡模拟,已经得到实验结果的良好检验.进一步的研究是该模型的直接数值模拟(direct numerical simulation,DNS)检验.本文对作者以及文献中报导的SOM模型DNS检验的研究进展进行了回顾.The existing turbulent combustion models either lack generality or are too computationally expensive for large-eddy simulation(LES).The paper proposed a statistical moment method based on the idea of turbulence modeling,called second-order moment(SOM)combustion model.It has been applied to both the Reynoldsaveraged Navier-Stokes modeling(RANS modeling)and LES of non-premixed jet flame and swirling nonpremixed flame and the LES of premixed bluff-body flame,and verified experimentally.Further studies should be conducted to validate the SOM model by direct numerical simulation(DNS).This paper gives a review of the advances in DNS validation of the SOM model proposed in this paper and that reported in literature.
