  "abstract": "<p>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 &ldquo;SingleBubble&rdquo; 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 &ldquo;PolydisperseStatic&rdquo; 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 &ldquo;PolydisperseStatic&rdquo; scan, the scanning position was fixed at &quot;Hxxx&quot; [mm]. The HDF5 files hold the reconstructed image data (dataset &ldquo;reco&rdquo;), each images scanning plane (dataset &ldquo;plane&rdquo;), and each images vertical scan position (dataset &ldquo;scanPosition&rdquo;).</p>"
