An Eulerian Scheme with Lagrangian Particles for Evaluation of Seakeeping Performance of a Ship in Nonlinear Wave, IJOPE

摘要

This paper deals with a design tool using CFD and criteria for ship structures under impact pressure loads due toudsloshing, slamming and green water. This study focuses on the development of numerical techniques for computing ???uidstructure interaction and for evaluating the seakeeping performance of a ship in nonlinear wave with breaking. This paperudalso presents a prediction of a local high-impact pressure caused by a strongly nonlinear wave. The developed numericaludmodel was applied to ship-wave interaction for evaluation of the seakeeping performance of a ship in waves. The heave,udpitch motion and added wave resistance were compared with experimental results and strip theory, and the results were inudquite good agreement with them. It can be seen that the proposed model can accurately capture a nonlinear free surfaceudwith wave breaking generated by a ship motion in wave and calm water.
