The entry of a circular cylinder into water represents the problem of the coupling of
multiphase flow with highly unsteady and nonlinear dynamics. Few studies have examined …

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 …

The growth, shedding, and collapse regime of cavitation under the effect of a free surface is
complicated by projectiles moving near and across the free surface and three phases (air …

Due to the complex three-dimensional flows such as fluid separation, fluid breaking and
bubble flows, accurate prediction of slamming loads on 3D ship bow is still limited. In this …

In this study, an attempt has been made to investigate the water-entry characteristics of the
high-speed parallel projectile numerically. The shear stress transport k-ω turbulence model …

The high-speed water entry dynamics and hydrodynamics of the projectiles are significantly
influenced by the head shape and initial velocity. In this study, we numerically investigated …
