摘要
以甲烷/空气的湍流射流非预混燃烧为对象,建立二维稳态湍流非预混火焰的小火焰模型。利用湍流流动模型和小火焰模型耦合求解,计算出速度、混合分数、温度以及反应标量的摩尔分数在燃烧室内的分布,模拟结果表明小火焰模型能够用来描述燃烧室内燃烧机理。
Based on the turbulent shoot non-premixed combustion of methane/air,build laminar flamelet model for two dimension steady state non-premixed turbulent reacting flows.Using turbulent flows model and laminar flamelet model couple to calculate,and work out velocity,mixture fraction,temperature and mole fraction of reactive scalar distribution in firebox.The result indicated that laminar flamelet model can used to describe the detail of combustion and heat transfer in firebox.
