摘要

The motion of single droplet on solid surface is a popular research topic, but most scholars have focused on stationary surfaces, there are few studies related to the motion of droplet on moving surface. In this paper, a visualization platform based on high‐speed photography is built to capture the morphology of droplet after impacting on moving surface, and to study the motion characteristics of droplet during impacting on moving surface. The evolution of the overall morphology of the droplet after impacting the moving surface is studied under different parameters such as the moving speed of the surface, the impact velocity of the droplet, the initial diameter of the droplet and the surface material, and the trends of the droplet spreading factor and the height factor are analyzed. The results show that the increase of surface movement velocity, droplet equivalent diameter, and droplet impact velocity all promote the spreading of droplet.
