3D-PTV Demo - Turbulent Jet

A 3D-PTV demo of a weakly turbulent jet, with some air bubbles. The jet is injected vertically upwards inside a glass tank full of water. The water is seeded with tracer particles at a rather high seeding density. The jet is weakly turbulent at a Reynolds number in the order of a few hundred ~500, and a nozzle diameter of ~ 1cm. The flow is generated by a peristaltic pump. <br><br>This dataset holds both raw data (images and binary "blob" files) that can be used to generate Lagrangian tracer trajectories, and a segment of post-processed data. Furthermore, there are videos and visualizations of the processed data and raw videos of the experimental apparatus. There is also a small number of python scripts that can help in the processing. The data open for free use, under a humble request of citation. <br><br>- Extensive description in the README file.- See the working example via Ipython notebook.<br><br>- For more information, please contact Ron Shnapp - [e-mail].

本数据集为掺有少量气泡的弱湍流射流三维粒子跟踪测速（3D-PTV）演示案例。射流通过直径约1cm的喷嘴垂直向上喷入盛满清水的玻璃水箱中，水箱内水体以较高浓度布撒示踪粒子。该射流处于弱湍流状态，雷诺数（Reynolds number）约为数百（~500），流动由蠕动泵（peristaltic pump）驱动产生。

本数据集包含可用于生成拉格朗日示踪轨迹（Lagrangian tracer trajectories）的原始数据（图像与二进制“Blob”文件），以及一段后处理数据集。此外，数据集还包含处理后数据的可视化视频、实验装置的原始录像，以及少量用于辅助数据处理的Python脚本。本数据集免费开放使用，恳请使用者在引用时注明来源。
