Interaction of waves with idealized high-relief bottom roughness, model parameters and code

Interactions between waves and large bottom roughness were investigated using Large
Eddy Simulations of oscillatory flow over infinite hemisphere arrays. Simulations were made
using the open source computational fluid dynamics code OpenFOAM. Wave amplitude, period,
and hemisphere spacing were varied to investigate the dependence of kinematics and dynamics
on dimensionless parameters, including the Keulegan-Carpenter number (KC), the ratio of wave
orbital excursion to roughness element size. This archive includes the input files and user
written routines to reproduce the simulations in the paper. Yu, X., J. H. Rosman, and J. L. Hench, 2018. Interaction of waves with idealized

本研究采用针对无限长半球阵列上振荡流动的大涡模拟（Large Eddy Simulation）方法，探究波浪与大尺度海底粗糙界面之间的相互作用。所有模拟均基于开源计算流体动力学（computational fluid dynamics, CFD）软件OpenFOAM完成。本研究通过调整波浪振幅、周期以及半球阵列间距，分析流动运动学与动力学特性对无量纲参数的依赖关系，涉及的无量纲参数包括凯鲁根-卡彭特数（Keulegan-Carpenter number, KC）以及波浪轨道位移与粗糙元尺寸的比值。本数据集档案包含可复现论文中模拟结果的输入文件与用户自定义程序。引用信息：Yu, X., Rosman J.
