摘要:
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
Abstract:
Based on the k - ε turbulent model and the improved EBU-Arrhenius combust ion model, the phenomena that the turbulence induced by obstacles w ill accelerate flame. The influence of obstacle is considered by specifying volume and area porosity and the additional source term in equat ions. The wal-l funct ion is chosen to t reat the near w all regions and the SIMPLE scheme is adopted to solve the equat ions. The developing process during which the turbulent flow induced by obstacles is coupled w ith the combustion. The positive feed back mechanism of mutual accelerat ion betw een turbulent flow and f lame is ex pounded.
