该文基于湍流的ｋ－ε模型和改进的ＥＢＵ－Ａｒｈｅｎｉｕｓ燃烧模型，对有障碍物情况下的湍流加速火焰现象建立了两维均相反应模型。障碍物对流场的影响不仅考虑到采用空度函数，还考虑了障碍物对流动产生的附加阻力的作用。壁面边界层区域则采用壁面函数法处理。选取Ｓｉｍｐｌｅ格式数值求解，其计算结果模拟了障碍物诱导的湍流与燃烧耦合作用下的流场的发生和发展的全过程，揭示了障碍物、湍流、火焰之间相互加速的正反馈机理
Based on the turbulent k-ε model and the improved EBU-Arhenius combustion model, a two-dimensional homogeneous reaction model for turbulence-accelerating flame phenomena with obstacles is established. The effect of obstacles on the flow field takes into account not only the use of the space function but also the effect of the obstacle on the additional resistance created by the flow. Wall boundary layer area is treated using the wall function method. The simple numerical solution is chosen. The calculation results simulate the entire process of the flow field induced by the obstacle-induced turbulence and combustion, revealing the positive feedback mechanism between obstacles, turbulence and flame accelerating each other
