拉格朗日质点法是模拟波浪破碎和越浪等水面剧烈运动的一种上级工具。为了进一步发展粒子法数值波浪水槽，仍然存在几个问题：亚粒子尺度湍流的建模，气相行为的建模，可动床（沉积物输运）的建模，以及浮体的建模。本文综述了作者发展的亚颗粒尺度湍流模型、固-液和液-气两相流模型以及浮体模型，介绍了颗粒方法在波浪破碎计算中的性能。(C)2005 Elsevier B. V.保留所有权利。
The Lagrangian particle method is a superior tool for the modelling of violent behavior of the water surface, such as wave breaking and overtopping. To further develop the numerical wave flume by the particle method, there remain several issues: modelling of the sub-particle-scale turbulence, modelling of the gas-phase behavior, modelling of movable bed (sediment transport), and modelling of floating bodies. In this paper, the sub-particle-scale turbulence model, the solid-liquid and liquid-gas two-phase-flow models, and the floating-bodies model, which have been developed by the authors, are reviewed to present the performance of the particle method in a computation of wave breaking.
