Comparative study of ultrafast X-ray tomography and wire-mesh sensors for vertical gas-liquid pipe flows
Banowski, M.; Beyer, M.; Szalinski, L.; Lucas, D.; Hampel, U.;
At the Institute of Fluid Dynamics of the Helmholtz-Zentrum Dresden-Rossendorf the wire-mesh sensor and the ultrafast X-ray tomography were developed to investigate two-phase flows with high spatial and temporal resolution. In the TOPFLOW facility, a test section was constructed for a comparative study of wire-mesh sensors and ultrafast X-ray tomography. Due to a minimum vertical distance between X-ray and wire-mesh positions, the results can be compared directly neglecting flow developing effects. Varying water and air superficial velocities in a wide range, flow regimes from bubble flow via slug flow to annular flow were investigated. Four typical experimental results are presented and discussed in this paper. Finally, the application ranges for both measurement techniques are briefly discussed.
