Dataset of turbulent flow over interacting barchan dunes

本数据集由坎皮纳斯州立大学机械工程学院创建，专注于研究水下交互式barchan沙丘上的湍流流动。数据集包含三个部分，分别对应单个沙丘和交互沙丘的PIV和PTV实验数据，总计包含数千个流场向量和图像数据。创建过程中，使用粒子图像测速（PIV）和粒子跟踪测速（PTV）技术，通过高速相机和激光系统捕捉沙丘表面的流体动态。该数据集主要用于研究自然界中沙丘的动态特性，预测沙丘场的行为，并评估其对地球及其他天体上人类活动的影响。

This dataset was developed by the School of Mechanical Engineering, University of Campinas, and focuses on the study of turbulent flow over submerged interacting barchan dunes. It consists of three sections corresponding to Particle Image Velocimetry (PIV) and Particle Tracking Velocimetry (PTV) experimental data for single and interacting dunes respectively, with a total of thousands of flow field vectors and image data. During its creation, fluid dynamics over the dune surfaces were captured using high-speed cameras and laser systems, employing PIV and PTV techniques. This dataset is primarily intended for researching the dynamic characteristics of natural dunes, predicting the behavior of dune fields, and assessing their impacts on human activities on Earth and other celestial bodies.
