Effect of viscosity on homogeneous–heterogeneous flow regime transition in bubble columns
Experiments were performed in a cylindrical 0.14 m diameter bubble column with a metal perforated plate. Air and aqueous solutions of glycerol with viscosity 1–22 mPa s were the phases. Gas holdup was measured and plotted against the gas flow rate. The critical point where the homogeneous–heterogeneous regime transition begins was determined by the drift-flux plot of the primary data. The homog...

15 صفحه اولLiquid phase dispersion in bubble columns operating in the churn-turbulent flow regime
The objective of this paper is to develop a reliable, yet-simple, correlation for the liquid phase axial dispersion coefficient Dax,L in bubble column reactors. In order to develop this correlation we carried out measurements of the centre-line liquid velocity VL(0) and Dax,L in bubble columns of diameter DT=0.174, 0.38 and 0.63 m with the air-water system. The measurements were performed in th...
متن کاملVisual Observation of Flow Regime Transition in Downward Vertical Gas-Liquid Flow Using Simple Mixer
Different flow patterns of downward gas-liquid two-phaseflow using simple mixer are studied in an experimental manner. An experimental setup is designed and fabricated to allow the visual observation of downward two-phase flow patterns and their transitions. The flow patterns are recorded by a 1200 frames per second high speed video camera. The quality of downward two-phase flow patterns photos...
