【 摘 要 】

References(9)Cited-By(7)The effect of clear liquid height and gas inlet height on gas holdup in a 0.16-m I.D. bubble column is theoretically and experimentally studied. From the gas balance in the bubble column, a three-region model is derived to express the effect of clear liquid height on gas holdup in the bubble column. This model can satisfactorily express the effect of the clear liquid height.The gas holdup decreases with increasing gas inlet height because of the decrease in effective clear liquid height. The effect of gas inlet height was well expressed by the three-region model using the effective clear liquid height.The meaning of different values of the critical clear liquid height in the previous works is explained by the three-region model.
