【摘要】 采用Monte Carlo法,综合考虑Y型喷嘴液膜破碎过程中表面扰动波长、液膜厚度及初始雾化液滴速度等分布的随机性,结合混合孔内气、液两相流动及二阶段雾化模型,建立Y型喷嘴雾化液滴粒度分布模型.利用FAM型激光粒度仪对实验喷嘴的雾化特性进行测试,测量结果与模型预测结果吻合较好.更多还原

【Abstract】 Based on the previous work in the literature,the random distribution characteristics of the wavelength of surfacedisturbance,the liquid sheet thickness,and the initial droplets velocity were modeled by using the MonteCarlo method.An improved mathematical modeling system with size distribution of droplets for Yjet nozzle was established.To verify the correctness of the model system,a laser diffraction sizedistribution analyzer was applied and several different Yjet nozzles were tested.Fairly good agreement between the experimental results and the model predictions was obtained.更多还原
