Hydrodynamic experimental benchmark data of bubbly two-phase pipe flow around a ring-shaped constriction

For the investigation of bubbly two-phase flow, which should serve as a future benchmark experiment for CFD code validation, an experimental study has been conducted at the <strong>T</strong>ransient Tw<strong>o-P</strong>hase <strong>Flow</strong> (TOPFLOW) facility at Helmholtz-Zentrum Dresden – Rossendorf (HZDR) using ultrafast electron beam X-ray tomography (UFXRAY). In this study, flow constrictions were installed into a pipe to create a generic three-dimensional flow field as an advanced test case for CFD codes. UFXRAY provide valueable data of the gas phase dynamics with high temporal and spatial resolution.

The provided data set contains the entire results of the experimental series L32 that uses a <strong>ring-shaped</strong> flow constriction with a blockage ratio of 0.5. 

An additional info.txt file provides all required information (e.g. nomenclature or binary file structure) and is, thus, necessary for interpretation of the experimental data.

为开展泡状两相流研究并为计算流体动力学（Computational Fluid Dynamics, CFD）代码验证提供未来基准实验，研究团队于德累斯顿罗森多夫亥姆霍兹中心（Helmholtz-Zentrum Dresden – Rossendorf, HZDR）的瞬态两相流（Transient Two-Phase Flow, TOPFLOW）实验装置中，采用超高速电子束X射线断层扫描（ultrafast electron beam X-ray tomography, UFXRAY）技术完成了一项实验研究。本研究在管道内加装流动节流装置，以构建通用三维流场，作为计算流体动力学代码的高级测试工况。超高速电子束X射线断层扫描可获取高时空分辨率的气相动力学优质数据。
本次提供的数据集包含实验序列L32的全部结果，该序列采用阻塞比为0.5的环形流动节流装置。
附带的info.txt文件包含解读本实验数据所需的全部信息（例如术语命名规则或二进制文件结构），因此是数据解析过程中不可或缺的文件。
