One of the promising solutions of dust accumulation on solar panels consists of using electric potential waves to prevent dust adhesion and to remove the dust layer. This study aims to understand the particle motion mechanisms on an electrostatic traveling wave conveyor. Understanding the effect of the operating parameters on particle trajectories and displacement distance is an essential step to improve the efficiency of this device and to understand the factors that can limit its performance. A numerical model that takes into account Coulomb force, dielectrophoretic, and image forces, but also gravity, drag force, and van der Waals adhesion force is carried out. The effect of rotating electric field, frequency, and electric potential harmonics on the particle trajectories and their characteristics are analyzed and discussed. The results reveal that the particles move according to four main movement modes. The frequency is a key parameter to control particle velocity and displacement. A hyper-synchronous movement during which the particles reach velocities much higher than the propagation velocity of the traveling wave has been obtained under certain conditions.

太阳能电池板上灰尘堆积的一种有前途的解决方案之一是使用电势波来防止灰尘附着并去除灰尘层。这项研究旨在了解静电行波输送机上的粒子运动机理。了解操作参数对粒子轨迹和位移距离的影响是提高该设备效率并了解可能限制其性能的因素的重要步骤。进行了考虑库仑力，介电泳和图像力，以及重力，拖曳力和范德华粘附力的数值模型。分析和讨论了旋转电场，频率和电势谐波对粒子轨迹及其特性的影响。结果表明，粒子按照四种主要运动方式运动。频率是控制粒子速度和位移的关键参数。在某些条件下，已经获得了超同步运动，在超同步运动中，粒子达到的速度远高于行波的传播速度。
