Abstract: The paper reports the results of studies which describe the influence of geometry and temperature on the liquid film coefficient, KL, and the mass transfer coefficient, KLa, for the transfer of oxygen from air bubbles rising in a liquid. It is shown that the liquid film coefficient is related to the total drag force operating at the liquid gas interface. The influence of several surface active agents on KLa and KL are reported. The study indicates that at low concentrations, the principle influence of surface active agents is their effect on the bubble size and rate of rise.
