Surface wettability significantly affects the dynamic behavior of impacting droplets. Recent studies have utilized the electrowetting (EW) effect to control the spreading and recoiling motions of droplets impacting hydrophobic substrates by modulating surface wettability. Electrowetting enhances droplet spreading while substantially reducing rebound tendencies. This study uses numerical methods to analyze the droplet’s behavior on a hydrophobic substrate under partial electrowetting conditions. When a droplet reaches its maximal spreading width, the electrowetting process is turned off. This method increases the maximal spreading width while decreasing the recoiling time compared to scenarios without electrowetting. Therefore, droplet rebounds from the surfaces quickly. Furthermore, the recoiling time decreases with higher frequencies and Weber numbers. Understanding the droplet dynamics has broad applications in areas such as self-cleaning surfaces, spray cooling, and microfluidic devices.
