Experimental study of effect of the surfactant type on dynamics of monodispersed bubble cluster rising in a viscous liquid

Abstract

The results of an experimental study of the process of contact ascent of the air monodispersed bubble cluster in the presence of surfactant in the range of Reynolds numbers Re < 0.2 are presented. New experimental data on the general picture of the contact ascent of the monodispersed bubble cluster in the presence of surfactant have been obtained. The effect of the nature of the surfactant on the overall picture of ascent, velocity and drag coefficient of the monodispersed bubble cluster has been analyzed.
