Abstract
Development and application of techniques to measure local properties of dynamic flows is in the focus of the work of the Institute of Fluid Dynamics at HZDR and of the AREVA Endowed Chair of Imaging Techniques in Energy and Process Engineering at TU Dresden. In this paper we report on the application of enhanced X-ray microradiography and microtomography techniques to measure Taylor bubble shapes in micro- and milli-channels. Further, experiments to investigate the mass transport and the influence of surfactants were conducted. The resulting flow structural data will foster meso- and microscalic numerical flow model development for small channel multiphase flow. Data and material of the presented study can be freely downloaded from the website of SPP 1506 (http://www.dfg-spp1506.de/taylor-bubble).
