摘 要:The axial and radial profiles of the gas holdup and bubble parameters in an external-loop airlift reactor of inner diameter 0.09 m and height 1.8 m were measured with the differential pressure method and dual-tip electrical conductivity probe at different superficial gas *** and water were used as the gas and liquid phases,*** experimental data of the average and local gas holdups,bubble size and its distribution,bubble rising velocity,bubble frequency and gas-liquid interfacial area were obtained,and were analyzed based on the gas-liquid flow field and bubble-bubble *** local gas holdup was correlated in terms of superficial gas velocity,axial height and radial position based on the experimental data.
