Abstract

In order to study the mechanisms of heat and mass transfer at the gas-liquid interfaces, flows inside and around a rising inert bubble are considered and calculated using the numerical algorithm developed in a companion paper. Studies on heat and mass transfer are carried out while special attention has been paid to the effects of wake vortices. Recoveries of the Sherwood and Nusselt numbers are observed in the wake zone behind bubbles and a physical explanation is proposed.

Additional Information: This paper study the mechanisms of heat and mass transfer related to a rising inert bubble using the numerical algorithm developed in our companion articles. It reveals that the steep concentration gradient in wake vortex can refresh the circulating flows and results in the recovery of heat and mass transfer. This provides a guiding clue to the increment of production capabilities in bubbly-flow-based chemical reactors.
