Gas holdup in bubble columns has been investigated over a wide range of operational and geometrical parameters. A criterion has been developed for the prediction of the transitional velocity from the homogeneous to heterogeneous flow regime. Correlations for gas holdup in both regimes are developed
In Lhe present study pressure transducer signals were used to measure the rate of liquid level drop during tbe bubble disengagement process. This enables one to use the dynamic gas disengagement method in opaque systems (i.e. industrial reactors operating at high pressures, and/or temperatures) and
The gas disengagement technique is discussed in detail and is applied in a two-dimensional bubble column and slurry bubble column to obtain the bubble size distribution. Flow characteristics including velocities of each phase and dispersed phase size distribution during the gas disengagement process
