Study on droplet behaviour in the gas–liquid coupled fan flow field

Abstract

The motion mechanism of the single droplet during wing cleaning of aeroengine is studied, and the force acting on the droplet entering the fan at low speed is analysed, and the motion model of a single droplet in swirl field is established. The influence of the main parameters such as droplet diameter, incident velocity and incidence angle on the droplet trajectory is analysed. The mechanism of droplet movement in the fan is described qualitatively.
