| 摘 要： | 喷雾湍流燃烧过程中,液滴、湍流和化学反应之间强烈耦合,物理化学机理非常复杂。本文将速度-标量-频率联合概率密度函数JPDF输运方程方法应用于两相喷雾湍流反应流问题,利用火焰面模型解耦流动和化学反应动力学的耦合关系,建立起相应的数值计算模型。采用Monte-Carlo数值计算方法,针对澳大利亚悉尼大学Masri等人以甲醇为燃料所进行的湍流喷雾燃烧值班火焰这一试验进行了数值模拟,通过与Fluent下的计算结果及试验结果的对比分析,验证了本文所建模型的准确性。

| Abstract: | In the turbulent spray flame,droplets,turbulent and chemical reaction are strongly coupled and the physical and chemical mechanisms are very complex.Velocity-scalar-frequency joint probability density function(JPDF) transport equation method was introduced into the two-phase turbulent reactive flow coupled with flamelet method for solving the relation between flow field and chemical dynamics.Based this model and the Monte-Carlo numerical method,the numerical simulation was performed for the turbulent spray ... |
