In this paper, we investigate the influences of nose shape, impact velocity (8–14 m/s), and
impact angle (60–90) on cavity dynamics when a projectile enters water. The Froude …

The water-entry problem is a complex multiphase hydrodynamic problem that is directly
related to many engineering applications and natural phenomena, such as torpedo airdrops …

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 study aims to experimentally investigate the vertical parallel water entry of two identical
spheres (in geometry and material) with different surface wettability (hydrophilic or …

The oblique water entry of hollow cylinders with four different apertures is investigated
experimentally at low velocities. The evolution characteristics of cavities, jets and splashes …

This study presents the experimental results of the vertical water entry of dimpled spheres.
The role of the number and arrangement of the surface dimples under different impact …

The water entry of hollow cylinders is investigated experimentally. Three hollow cylindrical
projectiles with the same mass, surface coating, outer diameter, holes' average diameter …

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 …

In the present study, we investigate the water entry of three hollow cylinders with fronts of
different fillet radii of 0, 5, and 10 mm. Particular attention is given to the effect of fillet radius …

We investigate cavity collapse regimes behind high-speed projectiles entering the water.
Using numerical simulations, we confirmed two different collapse phenomena: deep pinch …
