The water-entry problem is a complex multiphase hydrodynamic that directly related to many engineering applications and natural phenomena, such as torpedo airdrops, seaplane landings, ship slamming. Therefore, studying the influence of microscopic properties object surface on macroscopic phenomenon during water entry necessary. In this study, volume fluid model continuum force models are couple...

As part of the environmentally friendly policy ships, active research is being conducted on energy storage systems (ESS) for ships. This ESS has a major influence determining propulsion and operation system ship in future. A separate space must be provided ESS, but small medium-sized ships often require it to located at bottom make use available space. If ship, slamming impact load should consi...

Abstract This paper presents a comprehensive experimental study on the effect of extreme waves LNG carrier. The carrier model was equipped with variety sensors to measure motions, green water height deck as well local and global loads. Experiments in transient wave packets provided general performance terms response amplitude operators were accompanied by tests regular two different steepness. ...

We use the boundary element method (BEM) to study transient plane strain deformations of water induced by a rigid hull impacting at normal incidence initially stationary water occupying a half space with the goal of finding the hydrodynamic pressure acting on the hull. Water is assumed to be incompressible and inviscid, and its deformations to have zero vorticity. Thus deformations of water are...

‘Slamsex’ has emerged in gay vernacular recent years to denote a particular way of taking drugs and kind sex. Slamming refers this context the practice injecting – typically crystal methamphetamine intravenously. To pair ‘slamming’ with ‘sex’ is propose that mode drug administration constitutive sex relatively novel idea deserves some unpacking. What does it mean make route definitional delinea...

In this paper, we present a fully coupled computational fluid dynamic (CFD) and discrete module beam (DMB) method for the numerical prediction of nonlinear hydroelastic responses ship advancing in regular focused wave conditions. A two-way data communication scheme is applied between two solvers, whereby external pressure exported from CFD simulation used to derive structural DMB solver, deform...

This work represents a further step of the physical study documented by Greco and Lugni (2012b) and Greco et al. (2014). Three-dimensional experiments have been performed on a FPSO model in regular waves to investigate the occurrence of parametric roll, the occurrence and features of water on deck and bottom slamming and the sensitivity of the mid-ship bending moment experienced by the vessel t...
