The free-surface impact of solid objects has been investigated for well over a century. This
canonical problem is influenced by many physical parameters, including projectile …

Water entry bodies are one of the predominating sections in fluid dynamics. The study of
physics plays a vital role in understanding the forces, moments, and shape of the cavity …

This paper presents a comparative study on water entry and water walking events of elastic
spheres using a fluid–structure interaction method. The sphere displacements, cavity …

The objective of this work is to investigate the cavity dynamics during water entry of spheres
with varied structural density by a combined experimental and numerical method. Similar to …

The objective of this paper is to investigate the multiphase flow during water entry of spheres
with different surface wettability for low Froude numbers. In the experiment, a synchronous …

The process of water entry is a complex and attractive field of research, since from more than
a century ago there are wide applications in industry, nature science, bionics, and naval …

To investigate the complex cavity evolution, hydrodynamic action and motion response of a
stone impacting on the water, a calculation model is established with six degrees of …

Although skipping stones seems like a time-honored pastime, an in-depth study of this game
is of vital importance for the understanding of the water landing of space flight re-entry …

Water skipping has attracted significant focus in fluid dynamics, with extensive research on
rigid bodies contrasting with limited exploration into the dynamics of elastomeric bodies. At …

Deformable elastomeric spheres are evaluated experimentally as they skip multiple times
over a lake surface. Some spheres are embedded with small inertial measurement units to …
