We consider the liquid-side mass transfer coefficient k(L) in a dense bubble swarm for a wide range of gas volume fraction (0.45% and the vertical slip velocity . (C) 2011 Elsevier Ltd. All rights reserved.
The present work focuses on the collective effect on both bubble dynamics and mass transfer in a dense homogeneous bubble swarm for gas volume fractions alpha up to 30 %. The experimental investigation is carried out with air bubbles rising in a square column filled with water. Bubble size and shape are determined by means of a high-speed camera eq...
