Investigations on Polydisperse gas phase - Dynamic

This repository contains sequences of CT images of the two-phase flow in a bubble column consisting of a DN100-PN4 PVC pipe filled with water. 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 2,000 Hz. Data containers starting with “SingleBubble” contain image sequences of scans where a single bubble was injected at the bottom of the column using a magnetically operated valve which was open for the time specified in the directory name. Data containers starting with “PolydisperseDynamic” contain image sequences of scans where a background flow with 01 to 20 sl/min was induced via a needle sparger in addition to the single bubble (as described before). During each “PolydisperseDynamic” scan, the scan position was adapted to track the large bubble. The HDF5 files hold the reconstructed image data (dataset “reco”), each images scanning plane (dataset “plane”), and each images vertical scan position (dataset “scanPosition”).
