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。
The velocity-scalar-frequency joint probability density function (JPDF) transport equation method is applied to the two-phase spray turbulent flow. The flame model is used to decouple the coupling between the flow and the chemical reaction kinetics, and a corresponding numerical model is established. The Monte-Carlo numerical method is used to simulate the turbulent spray-on-duty flame with methanol as the fuel in the literature. The comparison between the calculated results and the experimental results shows that the proposed model Accuracy
