Free surface evolution from numerical wave tank simulations

An ensemble of two-dimensional numerical wave tank (NWT) simulations of breaking and non-breaking wave packets. The NWT uses the Gerris software package, a two-phase Navier-Stokes solver that utilises the volume-of-fluid method and explicitly models viscosity and surface tension effects. It is configured in non-dimensional coordinates scaled by the length and time characteristics of a deep-water wave with wavelength 1 m. A total of 6 experiments are included in the dataset, for which the wind speed, water depth, wave packet size and grid refinement level are varied. A full description of the NWT is provided in:

本数据集包含破碎与非破碎波浪群的二维数值波浪水槽（Numerical Wave Tank, NWT）模拟结果集合。该数值波浪水槽采用Gerris软件包搭建，其核心为两相纳维-斯托克斯求解器（two-phase Navier-Stokes Solver），采用流体体积法（Volume-of-Fluid Method, VOF），并对粘性与表面张力效应进行显式建模。该水槽基于波长1 m的深水波浪的特征长度与特征时间进行无量纲化，采用无量纲坐标系进行配置。本数据集共包含6组模拟试验，各试验分别改变了风速、水深、波浪群尺寸与网格加密等级。该数值波浪水槽的完整说明可参见以下文献：
