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 …

Bubbles have very important applications in many fields such as shipbuilding engineering,
ocean engineering, mechanical engineering, environmental engineering, chemical …

High-speed water entry is a transient hydrodynamic process that is accompanied by strongly
compressible flow, free surface splash, cavity evolution and other nonlinear hydrodynamic …

This paper aims to use the unified bubble dynamics equation to investigate bubble behavior
in complex scenarios involving hybrid free surface/wall boundaries and interactions …

The evolution of the water-entry cavity affects the impact load and the motion of the body.
This paper adopts the Eulerian finite element method for multiphase flow for simulations of …

We present the results of a combined experimental and theoretical investigation of the
vertical impact of low-density spheres on a water surface. Particular attention is given to …

This paper delves into the dynamics of a sphere entering flowing water at varying impact
velocities and flow speeds. Using a high-speed photography system and image processing …

Natural fibers with robust water repellency play an important role in adapting organisms to
various environments, which has inspired the development of artificial superhydrophobic …

We report on an experimental study of the trajectories of truncated cone projectiles on water
entry. The water entry trajectory stability is of great significance to the motion control of …

The water entry of cylindrical projectiles at high oblique speed has been investigated
experimentally and numerically. Projectiles with three types of noses and different lengths …
