Bubble Column에 있어서의 Gas Hold-up에 미치는 부유물의 영향에 관한 연구
A Study on the Effect of the Solid Suspension to the Gas Hold-up in the Bubble Column
The effect of the solid suspension to the gas hold-up in the bubble column was studied where by;
（1） The relation between the gas velocity (UG) and the gas hold-up (1-ψ) in the independent bubble flow range (UG≒0∼7 ㎝/sec) at different specific gravity of solid suspension and its weight was linear, while in the blow up flow range of bubbles the gas hold-up was constant to the gas velocity.
（2） In the independent bubbles flow range, the relation among the gas hold-up (1-ψ), the specific gravity (ρ) of solid suspension and its weight (W), the gas velocity (UG) appeared as follows;
