摘要：
The overall gas hold-tip is an important hydrodynamic parameter for bubble columns. This study provides new insights into the phenomena at the interface of gas-liquid systems influencing the gas hold-up in viscoelastic polyacrilamide (PAM) solutions. The influence of different parameters on gas hold up (superficial gas velocity, physical and rheological properties of the continuous phase, bubble mean diameter; bubble size distribution) was experimentally studied. The most important parameter proved to be the resistance of the interface due to the fluid elasticity which increased with the concentration of PAM solution.
