Paper Number: ISOPE-I-17-341
... loads. In terms of bow flare slamming, there are three main research directions: firstly, some researchers simplified the bow flare as a 2-D or 3-D wedge which has a similar dead rise angle, and then a series of water impact experiments and numerical calculations was carried out to study the slamming...

Paper presented at the The 26th International Ocean and Polar Engineering Conference, June 26–July 2, 2016
Paper Number: ISOPE-I-16-058
... Abstract As a part of a worldwide comparative study on water impact, this paper presents the numerical solutions of forces and pressures on a 2-D wedge section and a 2-D ship section. The highly non-linear water entry problem was simulated using a constrained interpolation profile (CIP) based...

... the structure and free surface at real sea. In this paper, experiments are carried out to study the water impact, which shows that the impact coefficient is quite closely related to the hull form shape and not highly correlated to the impact velocity. The experiments also find that the rise time of the impact...

Paper Number: ISOPE-I-12-561
... ABSTRACT By extending our mass-force model for the analysis of fluid-multibody interaction problems, we present some results for water impact created by a multibody moving in flows. We also investigate the effects of the air layer on water waves, comparing our one- and two-phase models. Both...

Paper Number: ISOPE-I-12-552
... it is important to accurately estimate global/local structural response of ships against slamming impact under bottom of ship bow. It was thought to be time-consuming and not practical to carry out water impact analysis with coupling both fluid and structure. However as a considerable development of computer...

..., written in an arbitrary Lagrangian-Eulerian (ALE) frame, are solved using projection schemes and a finite element method on unstructured grids. Numerical simulations of green water problems carried out in this study include: green water overtopping a fixed 2D deck; green water impact on a fixed 3D...

... ABSTRACT By extending LVOF (Li's VOF) to a two-phase model, we present some results for water impact created by the rigid bodies (landslide, cylinder and wedge) and study the effects of an air on water waves in a numerical wave tank. LVOF is a highly efficient Navier-Stokes solver, constructed...

Paper presented at the The Eighteenth International Offshore and Polar Engineering Conference, July 6–11, 2008
Paper Number: ISOPE-I-08-138
... ABSTRACT Based on our highly efficient Navier-Stokes solver, LVOF (Li, et al., 2004, 2007), we present some results for water entry and exit in a 3D numerical wave tank, by implementing our design of a mass-force coupling scheme for water impact (Li, et al., 2007a). LVOF is constructed...
