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.
