Study on separation performance of charged particles in rotating annular channel
In order to study the motion and deposition characteristics of charged particles in the charged rotating annular channel,the computational fluid dynamics with two-phase flow discrete particle method was used to simulate the motion of the charged particles in the charged rotating annular channel.According to the simulation results,the effects of different particle size,voltage,inlet Reynolds number and channel parameters on the movement and deposition of charged particles have been analyzed.The competitive relationship between the centrifugal force and the electric field force of the charged particles in the rotating channel has been studied,and the motion and deposition of the charged particles caused by the centrifugal force and the electric field force were explored.The results show that a single particle with different particle sizes has different escape voltage intervals.The size of the interval increases with the increase of particle size,and the width of the interval decreases significantly with the increase of aspect ratio.For the escape rate curves of multiple particles,particles with different diameters will have different degrees of intersection.With the increase of the aspect ratio,the height and cross of the escape rate curves of particles will decrease significantly,while with the increase of the rotational speed,the intersection of the escape rate curves of particles will decrease to a certain extent,and the height will not change significantly.
