Effect of impeller diameter to vessel diameter ratio on gas holdup
Numerous gas holdup correlations have been developed for predicting gas holdup in agitated vessels. However; gas holdup studies were only limited to the use of impeller diameter to vessel diameter ratio (Di/DT) of approximately 1/3. None of the available correlations considered the effect of (Di/...

| Summary: | Numerous gas holdup correlations have been developed for predicting gas holdup in
agitated vessels. However; gas holdup studies were only limited to the use of impeller
diameter to vessel diameter ratio (Di/DT) of approximately 1/3. None of the available
correlations considered the effect of (Di/DT) variation on gas holdup. This work was
carried out to investigate this effect. The results of this investigation showed that the
gas holdup increases with (Di/DT) ratio. The effect of (Di/DT) variation on gas holdup
was correlated, with e = 2.0(NaNFr)O.6NRe
0.1 (Di/DT)2.5 , for an air-water mixture. The
(Di/DT) used in this work ranged from 0.36 to 0.53 |
