  • Interface resistance of sliding water droplet at constant velocity on inclined solid surface

抄録

<p>The slipperiness of the droplet is important for removing the droplet from various solid surfaces. The slippery surface can be used for products and structures that require antifouling and waterproofing. In order to develop a highly slippery surface, it is necessary to predict the sliding behavior of droplets. This study focused on the relationship between the sliding behavior of water droplets on an inclined solid surface and interfacial resistance in order to investigate the behavior of water droplets after they began to slide. Water droplets are dropped on a solid surface inclined at various angles, and then the sliding speed, contact angle, and width of the solid-liquid interface are measured. In addition, a sliding angle experiment was conducted to observe the behavior of water droplets when the time-varying inclination angle of the solid surface. As results of the experiment, it was found that the water droplet slipped at a constant velocity, and the interfacial resistance at that time was found to be balanced with the slope direction component of gravity.</p>
