摘要

Inspired by the phenomenon of stone-skipping in life, the problem of continuous water-skipping in trans-media vehicles is widely concerned, which is characterized by multiphase flow-solid coupling, dynamic boundary, liquid surface fragmentation and high impact loads. Based on the Moving Particle Semi-implicit numerical method, this paper investigates the disc's motion characteristics and liquid surface variation, focusing on the influence of the water entry parameters on the sloshing phenomenon of the water-skipping. The simulation results indicate that the disc water skipping process can be divided into three stages: water entry, sliding and re-flying, during which the disc is with large impact loads and the water surface is with large scale breaking and droplet splashing. With certain rotation velocity, the disc could maintain a smooth water skipping, while there will be a lateral displacement due to the Magnus effect. The larger the water-entry velocity and angel is, the larger impact load is, the faster velocity decay rate is, the larger vacuole area is, and larger the water surface broking area and the droplet splashing is. Predicted water-skipping phenomenon agrees well with the experimental result obtained from high-speed photography.
