摘      要：Using a five point conductivity technique local values of bubble size,bubble velocity and gas fractionhave been experimentally determined in a 288 mmID and 4.3 m high bubble column as a function of axial andradial position for the air/water and CO2/N2/aqueous MDEA *** experimental results are comparedwith predictions from a fundamental two-fluid *** implementation of a non-steady lateral drag term inthe two-fluid model has been *** addition to improving the physical realism of the model,it is found togive slight improvements in the predictions of the distributions of local bubble *** of bubble size arefound in reasonable agreement with experimental values in the heterogeous flow regime,whereas they are stil1found to be unreliable at low gas *** void predictions are found in reasonable agreement with experi-mental values,but deviations occur in the homogeneous flow regime towards the *** is attributed to defi-ciencies in the simplified bubble size
