【 摘 要 】

References(15)Cited-By(14)Gas holdup, bubble size distribution and gas absorption capacity coefficient in a multi-stage gas-liquid spouted vessel are observed in this study and it is confirmed that coalescence of gas bubbles observed in the calm uniformflow section in a single-stage spouted vessel can be avoided by introduction of perforated plates. Experimental results show that effect of physical properties of liquid on the capacity coefficient in a spouted vessel is more similar to that observed in an aerated mixing vessel than to that of a bubbling column. It is also observed that the gas absorption coefficient is proportional to the square root of the Sauter mean bubble diameter.
