Simulation dataset for "Numerical analysis of flow and stress redistribution at an open-to-closed channel transition caused by floating debris carpets"

This dataset contains the results of various channel configurations (detailed in the attached document) using Direct Numerical Simulation (DNS) technique. The objective of this research is to understand flow transitions occurred to the plastic debris accumulation in the open channel. We studied these fundamental phenomena using high-fidelity numerical simulations. In this dataset, we provide the flow statistics, such as flow velocity, Reynolds stresses and shear stresses, in Python Numpy format.

本数据集收录了采用直接数值模拟（Direct Numerical Simulation, DNS）技术开展的多种槽道构型数值计算结果，详细参数说明见附件文档。本研究旨在揭示明槽内塑料碎屑堆积过程中出现的流动转捩现象，通过高精度数值模拟手段对这类基础流动现象进行了系统探究。本数据集以Python NumPy格式提供了流动速度、雷诺应力与切应力等核心流动统计量。
