Download movie (2.44 MB)The movies previews below show gas bubbles ascending from the gas distributor into the riser section of the airlift column at three superficial gas velocities, UG = 1.27, 2.93 and 4.73 cm/s, without and with vibration (superficial gas velocity is defined with respect to the riser cross-sectional area). To view the movies in real time, you are encouraged to download them. Click on the previews shown or on the links given.

The previews below show gas bubbles at the top of the riser section (in the gas-liquid separator section) in the airlift column at three gas velocities, without and with vibration. The top section of the riser shown in the movies corresponds to a distance of approximately 1 cm below the dispersion height in the gas-liquid separator, depending on the gas velocity. Tiny air bubbles can be seen to be dispersed in the liquid of the gas-liquid separator. These bubbles become more pronounced with an increase in the superficial gas velocity.
