Processed flow field dataset for "Flow structure characteristics in bend-straightened reaches of continuous bend channels"

This dataset provides the main flow field data obtained from the numerical simulations reported in the paper. The data are released for reference, verification, and further analysis by interested readers. The dataset includes three dimensional spatial coordinates, velocity components, fluid volume fraction, and turbulent kinetic energy under different simulation cases. The data are provided in .dat format and can be read and visualized using MATLAB, Python, or other post-processing software. For consistency with the paper, the coordinate system in this dataset has been adjusted according to the coordinate definition used in the manuscript. The directions of the coordinate axes, the coordinate origin, and the arrangement of the variables are consistent with the descriptions in the paper. Based on the released data, readers may extract sectional flow fields, free-surface distributions, turbulent kinetic energy distributions, and other relevant hydrodynamic parameters according to their own research needs. The purpose of releasing this dataset is to improve the reference value and reproducibility of the reported results and to provide supporting data for numerical simulation and comparative studies of similar hydrodynamic processes.本数据集提供了该论文中报道的数值模拟所得的主流场数据。本数据集公开发布，供有需求的读者参考、验证并开展进一步分析。数据集包含不同模拟工况下的三维空间坐标、速度分量、流体体积分数及湍流动能。数据以.dat格式存储，可通过MATLAB、Python或其他后处理软件读取并可视化。 为与论文保持一致，本数据集的坐标系已根据稿件中采用的坐标定义进行调整。坐标轴方向、坐标原点及变量排布均与论文中的描述保持一致。基于本公开发布的数据，读者可根据自身研究需求，提取截面流场、自由表面分布、湍流动能分布及其他相关流体力学参数。本数据集发布的目的在于提升已报道研究结果的参考价值与可复现性，并为同类流体力学过程的数值模拟及对比研究提供支撑数据。
