摘要

利用基于光滑粒子流体力学的dualspphysics建立了圆形波盆的数值模型，以产生短波峰波。利用Pierson Moskowitz谱和带扩展值s的cosin2s扩展函数实现了短波峰的再现。利用168个铰链襟翼型造波器，该数值水箱模型不仅能成功再现长波峰，而且能成功再现短波峰。

Numerical Simulation of Multidirectional Waves With Full-Spectrum Using DualSPHysics

The numerical model for circular wave basin were developed using DualSPHysics based on Smoothed Particle Hydrodynamics to generate short-crested wave. The recreation of short-crested wave was achieved using Pierson Moskowitz spectrum and cosin2s spreading function with spreading value s. It is found that this numerical tank model could successfully reproduced not only long-crested but short-crested waves using 168 hinged-flap type wave makers.
