Response of flow and saltating particle characteristics to bed roughness and particle spatial density

The data were used in the paper "Response of flow and saltating particle characteristics to bed roughness and particle spatial density" which was submitted to "Water Resources Research". In this paper, The numerical model combining LES method and point-particle method is applied for tracking particle trajectories. The effects of bed roughness and particle spatial density on the bedload transport are investigated by numerical simulations. The distributions of key parameters for saltation, including their changes, are assessed using the PDF curves.

本数据集应用于投稿至《水资源研究（Water Resources Research）》的论文《水流与跃移颗粒特性对床面粗糙度及颗粒空间密度的响应》（Response of flow and saltating particle characteristics to bed roughness and particle spatial density）。该论文采用耦合大涡模拟（Large Eddy Simulation，LES）与点颗粒法的数值模型，对颗粒运动轨迹进行追踪。本研究通过数值模拟，探究了床面粗糙度与颗粒空间密度对推移质输运的影响，并借助概率密度函数（Probability Density Function，PDF）曲线，对跃移运动关键参数的分布及其变化特征开展了评估分析。
