CFD Simulation of Motion Response of a Trimaran in Regular Head Waves

International Journal of Maritime Engineering, 2020
CFD has proved to be an effective method in solving unsteady Reynolds–Averaged Navier-Stokes (RANS) equations for analysing ships in free surface viscous flow. The research reported in this paper is intended to develop a better understanding of the parameters influencing high-speed trimaran motions responses. Variations of gridding system and time step

Unsteady PIV for regular head waves

SNAME 26th American Towing Tank Conference, 2001
Phase-averaged results from a towing tank experiment of regular head waves are documented. Uniform flow, free surface elevation, and headwave flowfields are measured with a towed particle image velocimetry system in the Iowa Institute of Hydraulic Research towing tank of a two-dimensional, deep-water, long­wavelength (A.=4.572 m), low wave steepness ...

CFD Simulation of Flexible Ship in Regular Head Waves

Volume 9: Odd M. Faltinsen Honoring Symposium on Marine Hydrodynamics, 2013
The ship springing is continuous vibration of the hull girder due to encountered wave excitation, which is considered as a typical fluid-structure interaction (FSI) problem. In this study, a CFD approach is proposed for modeling ship springing induced by large amplitude regular waves.

URANS Simulation of ONR Tumblehome Parametric Rolling in Regular Head Waves

Volume 2: CFD and FSI, 2019
Abstract In this paper, an in-house CFD code HUST-Ship is used for the numerical simulation of parametric rolling phenomena of ONR Tumblehome in regular head wave. Preliminary resistance and roll decay simulations at Fr = 0.2 were carried out and compared with existed INSEAN experimental data.

Numerical Simulation of Surface Ship Motion in Regular Head Waves

Volume 2: CFD and FSI, 2018
The motion of surface ship in wave environments is fully three-dimensional unsteady motion and includes complex coupling with hydrodynamic force and dynamic motion of the rigid body. This paper presents simulations of the KCS model with motions involve pitch and heave in regular head waves.
