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 …

For centuries, bubbles have fascinated artists, engineers, and scientists alike. In spite of
century-long research on them, new and often surprising bubble phenomena, features, and …

The ice floating on water surfaces during winter significantly influences the water entry
process of a cylinder. Therefore, it is crucial to evaluate the influence mechanism of the ice …

We present a study of the forces during free-surface water entry of spheres of varying
masses, diameters, and surface treatments. Previous studies have shown that the formation …

At the beginning of the last century Worthington and Cole discovered that the high-speed
jets ejected after the impact of an axisymmetric solid on a liquid surface are intimately …

Diving induces large pressure during water entry accompanied by the creation of cavity and
water splash ejected from the free water surface. To minimize impact forces, divers …

We show how the deposition of laser energy induces propulsion and strong deformation of
an absorbing liquid body. Combining high speed with stroboscopic imaging, we observe …

An ice-constrained environment significantly affects the water entry of projectiles. In this
paper, cavity evolution in the presence of floating ice is studied. The numerical method is …

This article reports experimental insights into the physics of water entry of hydrophobic
spheres. In the set of experiments, parameters such as sphere density, diameter, and impact …
