Abstract
Air sparged into highly viscous media divides into a nearly bimodal large and small bubble population. It has been assumed, often erroneously, that the small bubbles are not actively transferring oxygen. Our studies (funded by SERC) have shown that the opposite is true: small bubbles play a key role in oxygen transfer, especially in impeller agitated reactors. In this project we aim to use methods already established by us to determine how process conditions affect the hold up and bubble size distribution; determine experimentally the relative oxygen transfer rates; investigate the effects of scale on oxygen transfer to highly viscous liquids; and develop a comprehensive model for gas-liquid mass transfer in highly viscous biological media.
