Abstract:

This study aims to address the problem of electrostatic deposition in aircraft by exploring the electrification voltage of typical materials. The focus is on understanding the change in electrification voltage after collisions between typical materials and air particles at different collision angles and speeds. This research approach involves a combination of simulation tests and analysis, with the goal of understanding the influence of collision angle and speed of air particles on the electrification of typical materials as well as preliminarily unveiling the change law of electrification voltage of certain materials. The results show that the electrification voltage of the typical material increases approximately linearly with an increase in collision angle and speed. The collision speed affects the contact area and mode, while the collision angle affects the proportion of different modes in the contact area, both of which impact the change in electrification voltage of typical materials.

Key words: electrostatic deposition, typical material, air particles, collision angle, collision speed
