单颗粒撞击颗粒覆层表面的实验研究
Experimental study on the impact of single particles on the surface of particle coatings
摘要
Abstract
Based on the issue of significant impact caused by dust accumulation on the surface of photovoltaic modules on power plants,experimental studies on the impact characteristics of silica particles on the coating surface under different particle coating thicknesses and void ratios are carried out.The experiment used a high-speed camera to measure the incident velocity and rebound velocity of particles,focusing on exploring the influence of particle coating thickness and void ratio on adhesion probability and average recovery coefficient,analyzing the energy loss after particles impact the coating,and fitting the relationship between particle coating thickness,void ratio and critical capture velocity.The results show that the adhesion probability of particles decreases with the increase of incident velocity.Under the same incident velocity,the thicker the particle coating and the greater the void ratio,the higher the adhesion probability,the smaller the average recovery coefficient,and the higher the normalized energy loss.关键词
