摘要:为了优化飞轮造雾系统雾化液滴的粒径分布,采用数值模拟方法,探究飞轮造雾系统的雾滴粒径随着导流板安装角度的变化规律。通过建立飞轮造雾主体三维模型,设置导流板5种安装角度、3种工况,利用FLUENT软件对飞轮造雾系统的雾化效果进行模拟,并对雾化过程进行可视化研究。结果表明:导流板的合理设置对飞轮造雾系统雾化液滴粒径减小有促进作用;导流板安装角度由30°增大至50°的过程中,飞轮造雾系统出口雾滴平均粒径逐渐减小。模拟结果与试验结果变化趋势基本相同,两者具有良好的相关性。

Abstract:In order to optimize the atomization droplet size distribution of the flywheel fogging system, the numerical simulation analysis method was used to study the variation of the droplet size of the flywheel fogging system with the installation angle of the deflector. The three-dimensional model of the flywheel fogging main body was established. The atomization effect of flywheel fogging system was simulated with FLUENT software by setting five installation angles and three working conditions of the system, and the atomization process was visualized. The results showed that the reasonable setting of the deflector could promote the reduction of atomized droplet size of the flywheel fogging system, and the mean diameter of droplets at the outlet of flywheel fogging system decreased gradually as the installation angle of the deflector increased from 30° to 50°. The change trend of the simulation results was basically the same as the experimental results, and they two had a good correlation.
