Hydrodynamic investigations of gas-liquid two-phase flow in centrifugal pumps - reconstructions (selected data)

This data repository contains reconstructed and quantitatively analyzed gas-liquid two-phase distributions obtained from a centrifugal pump mock-up whose geometry is related to a commercially available industrial centrifugal pump. As measurement system the ultrafast electron beam X-ray CT scanner (UFXCT) is applied with a frame rate of 2,500 Hz, single-plane mode and a total scanning interval of 5 seconds. The data repository contains: Reconstructed raw data (FBP) sets for selected two-phase flow operating conditions at constant 1480 rpm with static and rotating impeller, respectively Corresponding quantitative gas fraction data sets (for static impeller position) Averaged gas fraction distributions Standard deviations of the gas fraction mean values Data evaluation scripts
