    Abstract
  • Based on Eulerian theory, the droplet impingement characteristics of the spinner were simulated. The droplet impingement characteristics of the spinner were achieved by calculating the droplets' flow field with numerical diffusion. The rotate speed impact on the droplet impingement characteristics of spinner was analyzed. Results show that the greater the rotate speed, the smaller the droplet impingement limit. In typical flight conditions and weather conditions, the centrifugal force on the trajectory of droplets is much smaller than the inertial force. The rotate speed has little influence on the droplet impingement characteristics of the spinner.
