Abstract

Abstract

Water-entry experiments were carried out by adopting five kinds of surface roughness to explore the effects of surface roughness of water-entry spheres on the evolution of cavities induced the water-entry of the spheres and the motion characteristics of the spheres during the water-entry process of the spheres. The experiments were based on an open water-tank test system. Meanwhile, a high-speed camera was used to record the water-entry processes of the spheres with different surface roughness. The evolutions of cavity, splash and motion characteristics of each sphere were obtained. It is found that the closure of cavity and splash will exert a negative acceleration on the sphere. By comparing the displacement, velocity and acceleration curves of the spheres with different surface roughness, it is found that the sphere with the largest surface roughness will move significantly slower than other spheres after the end of slamming, and that the effects of surface roughness on the sphere motion are mainly reflected in the early period of the water-entry. By analyzing the shrinkage of the cavities connected with the free surface of each sphere after cavity seal, it is found that both the shrinking velocity and acceleration curves take on extreme points, and that the larger the surface roughness of the spheres, the earlier the extreme point appears.
