Study on the Influence of Electrostatic Force on Collision Efficiency between Micro-Particle

Abstract This paper is mainly about the impact of electrostatic forces on the collision efficiency, whinch collision is caused by the internal forces between micro-particles. The Fourth-order Runge-Kutta method is used to solve the dynamical equations of the micro-particle collision. Studies have shown that the micro-particles with the same charge have the same initial velocity, the larger the volume of the particles, the more the charge amount, and the different particle size has a greater impact on the repulsion effect during the collision. That is, the repulsion effect exhibited in the collision between particles is related to the particle size; Micro-particles with different kinds of charges have the same initial velocity, the smaller the volume, the less the charge amount, and the smaller the particle size, the more attractive the collision effect during the collision.
