本文概述了非线性势流求解器在水波传播中的实际应用。这些数值模型无法明确描述波浪破碎现象，包括自由表面重新连接、能量耗散等。这减少了它们在真实海浪中的应用范围，而真实海浪是最普遍的不规则和定向波场。这项研究涵盖了离散化、水深、方向扩展和频谱峰值对此类非线性势模型的使用限制的影响。使用的方法依赖于基于高阶谱方法的高度非线性模型。
This paper presents a general overview of the practical applicability of non-linear potential flow solvers for water wave propagation. Those numerical models are unable to describe explicitly the wave breaking phenomena, including free surface reconnexion, energy dissipation, etc. This reduces their range of application in real sea waves, which are in the most general context irregular and directional wave fields. This study covers the influence of discretization, water depth, directional spreading and spectral peakedness on the limitations in the use of such non-linear potential models. The approach at use relies on a highly non-linear model based on the High-Order Spectral method.
