Windisch, Dominic Barthel, Frank Bieberle, André Windisch, Dominic 2024-12-17 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”). https://rodare.hzdr.de/record/3344 10.14278/rodare.3344 oai:rodare.hzdr.de:3344 eng url:https://www.hzdr.de/publications/Publ-40434 doi:10.14278/rodare.3343 url:https://rodare.hzdr.de/communities/rodare url:https://rodare.hzdr.de/communities/rofex url:https://rodare.hzdr.de/communities/topflow info:eu-repo/semantics/restrictedAccess ultrafast X-ray computed tomography bubble column Investigations on Polydisperse gas phase - Dynamic info:eu-repo/semantics/other dataset

Barthel, Frank Sprewitz, Uwe Sohr, Johanna Schubert, Markus Bieberle, André Sohr, Johanna Barthel, Frank Sprewitz, Uwe Schubert, Markus 2024-10-21 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 B1-750 (specific geometric surface area is 750 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. https://rodare.hzdr.de/record/3204 10.14278/rodare.3204 oai:rodare.hzdr.de:3204 eng url:https://www.hzdr.de/publications/Publ-39766 doi:10.14278/rodare.3203 url:https://rodare.hzdr.de/communities/fwd url:https://rodare.hzdr.de/communities/hzdr url:https://rodare.hzdr.de/communities/rodare url:https://rodare.hzdr.de/communities/rofex url:https://rodare.hzdr.de/communities/topflow info:eu-repo/semantics/restrictedAccess sandwich packings two-phase flow ultrafast electron-beam X-ray CT CT image sequences of sandwich packings: B1-250 plus B1-750 at constant liquid rate of 10 m³/(m²h) and various gas rates info:eu-repo/semantics/other dataset

Windisch, Dominic Barthel, Frank Bieberle, André Windisch, Dominic 2025-01-06 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 “PolydisperseStatic” 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 “PolydisperseStatic” scan, the scanning position was fixed at "Hxxx" [mm]. The HDF5 files hold the reconstructed image data (dataset “reco”), each images scanning plane (dataset “plane”), and each images vertical scan position (dataset “scanPosition”). https://rodare.hzdr.de/record/3363 10.14278/rodare.3363 oai:rodare.hzdr.de:3363 eng url:https://www.hzdr.de/publications/Publ-40432 doi:10.14278/rodare.3362 url:https://rodare.hzdr.de/communities/fwd url:https://rodare.hzdr.de/communities/hzdr url:https://rodare.hzdr.de/communities/rodare url:https://rodare.hzdr.de/communities/rofex url:https://rodare.hzdr.de/communities/topflow info:eu-repo/semantics/restrictedAccess ultrafast X-ray computed tomography bubble column Investigations on Polydisperse gas phase - Static info:eu-repo/semantics/other dataset
