The aim of this study was to develop a practically usable model to describe the influence of mcreased gas density on the gas holdup m bubble column reactors. In order to develop an insIght into this effect, we performed extensive sets of experiments at pressures ranging from 0.1 MPa to 2 MPa and wit
Electrical conductivity has been used to measure local gas holdup in the bubbling zone (holdup C&30 %) and froth zone (holdup 695 %) ofa flotation column. Models have been developed to cover the full range of dispersed phase volume fraction, based on tortuosity or effective path between electrodes.
Noise analysis techniques are used to construct bubble velocity and gas holdup profiles in an air/water bubble column. It is shown that the use of a laser renders reliable and consistent results. A comparison with local data obtained with a four-point glasfiber probe and the drift flux model of Bame
