CT image sequences of sandwich packings: B1-250 plus B1-500 at constant liquid rate of 50 m³/(m²h) and various gas rates

This repository contains sequences of CT images of the two-phase flow in sandwich packings that are alternately arranged in a packing stack using B1-250 (specific geometric surface area is 250 m² /m³) for de-entrainment layer and B1-500 (specific geometric surface area is 500 m² /m³) for holdup layer. As measurement system the ultrafast electron beam X-ray computed tomography scanner was applied in dual plane scanning mode with a dual-imaging frequency of 1000 Hz. Operating parameters, the scanning plane as well as the tags "AB" for de-entrainment layer, "AN" for hold-up layer and "DRIVE" for an axial scan are encoded in the name of the data files.

本数据集仓库包含夹层填料床内两相流的CT（Computed Tomography）图像序列。该填料床采用交替排布结构，其中除雾层使用比表面积为250 m²/m³的B1-250填料，持液层使用比表面积为500 m²/m³的B1-500填料。本研究采用超快电子束X射线计算机断层扫描（ultrafast electron beam X-ray computed tomography）扫描仪，以双平面扫描模式运行，双成像频率为1000 Hz。数据文件名中编码了操作参数、扫描平面信息，以及用于标识不同类型的标签："AB"对应除雾层，"AN"对应持液层，"DRIVE"对应轴向扫描。
