Liquid fraction investigations in a RPB with different foam and liquid inlet geometries using GammaCT

For liquid fraction investigations in a rotating packed bed (RPB) angular-resolved time-averaged gamma-ray computed tomography (GammaCT) is applied. Liquid is injected via different inlet geometries. This repository mainly contains the reconstructed CT data for the following configurations: solid foam, 12 baffle liquid inlet solid foam, 32 baffle liquid inlet solid foam, single point liquid inlet printed small zick-zack foam, multi point liquid inlet printed small zick-zack foam, zero point liquid inlet printed big zick-zack foam, multi point liquid inlet Furthermore, the corresponding restructured sinogram raw data are included as well as diverse radiographic scans from different foam geometries that are used to arrange the RPB disc and the CT scanning plane as planar as possible and to define the vertically distributed scanning planes within the foams.

为开展旋转填充床（Rotating Packed Bed, RPB）内液相分数的相关研究，本研究采用角分辨时间平均伽马射线计算机断层扫描（GammaCT）技术。实验中通过不同入口结构注入液相物料。本数据集仓库主要包含以下配置方案的重建CT数据：实心泡沫、带12个挡板的液体入口实心泡沫、带32个挡板的液体入口实心泡沫、单点液体入口打印制备的小型锯齿泡沫、多点液体入口打印制备的小型锯齿泡沫、零液体入口打印制备的大型锯齿泡沫，以及多点液体入口配置的相关数据。此外，仓库中还收录了对应的重构正弦图原始数据，以及针对多种泡沫结构的多组射线成像扫描结果；这些扫描数据用于将旋转填充床圆盘与CT扫描平面尽可能调整为共面，并用于确定泡沫内部沿垂直方向分布的各扫描平面。
