Experimental dataset for "Stability of an Idealized Floating Carpet of Plastic Spheres in an Open Channel Flow"

Experimental dataset conducted at the Hydraulic Engineering Laboratory (TUDelft, CITG) for the peer-reviewed article "Stability of an Idealized Floating Carpet of Plastic Spheres in an Open Channel Flow". <br>Plastic debris can accumulate at hydraulic structures and waste-collection devices, leading to a so-called <em>floating carpet </em>formation. Understanding the accumulation of plastic debris at structures is pivotal in the prediction of increased flood risk and design of waste-collection devices. In this research, we studied the stability of plastic carpets under different flow conditions using laboratory experiments, and we developed analytical models to predict critical velocities that led to two instabilities. <br>This dataset contains1. Data for analysis of instability, squeezing and erosion, for the carpet (contained in 2cmCarpet.csv file), and2. Data for velocity measurements using Laser Doppler Anemometary (LDA) (contained in 2_00meterCarpet.pickle file).<br>Water level was measured using Microsonic acoustic displacement sensor (model - mic+35/IU/TC). Flow discharge was measured using Proline Prosonic Flow 91W ultrasonic flow meter. Flow velocity is measured with LDA system.<br>

本数据集源自代尔夫特理工大学（TUDelft）水利工程实验室（CITG）为同行评审学术论文《明渠水流中理想塑料浮毯的稳定性》（"Stability of an Idealized Floating Carpet of Plastic Spheres in an Open Channel Flow"）所开展的实验研究。塑料废弃物可在水利构筑物与垃圾收集装置处聚集，形成所谓的浮毯（floating carpet）。明晰塑料废弃物在构筑物处的聚集规律，对预测洪水风险升高以及优化垃圾收集装置设计均具有关键意义。本研究通过室内实验探究了不同水流条件下塑料浮毯的稳定性，并构建了解析模型以预测引发两类失稳现象的临界流速。本数据集包含两部分数据：1. 用于浮毯失稳、挤压与侵蚀现象分析的实验数据，存储于2cmCarpet.csv文件中；2. 采用激光多普勒测速仪（Laser Doppler Anemometary, LDA）测得的流速数据，存储于2_00meterCarpet.pickle文件中。水位采用Microsonic声学位移传感器（型号：mic+35/IU/TC）进行测量；流量采用Proline Prosonic Flow 91W超声波流量计进行计量；水流流速通过LDA系统测得。
