中文摘要：

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,建立相应的数值计算模型。采用Monte-Carlo数值计算方法,针对文献中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,验证了所建模型的准确性。

英文摘要：

In the spray turbulent combustion,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 on this model and the Monte-Carlo numerical solving method,the numerical simulation was performed for the turbulent spray combustion in a piloted jet flame burner developed by Masri.The comparison between the experiment and the numerical simulation results verified the spray JPDF model.
