Abstract
The paper presents the results of experimental study for rising a cluster of monodispersed gas bubbles in viscous liquid with/without surfactant for the Reynolds number in the range Re = 0.01–1. The influence of the surfactant type on the dynamics of bubble cluster rising has been analyzed. The qualitative pattern of monodispersed bubble cluster rising was defined as a function of initial void fraction in the range CV = 0.001–0.04. New experimental data were obtained on velocity and drag coefficient for a compact cluster made of monodispersed bubbles rising in a liquid with/without surfactant (both for contact and contactless type of bubble rising).
期刊介绍：
The journal Thermophysics and Aeromechanics publishes original reports, reviews, and discussions on the following topics: hydrogasdynamics, heat and mass transfer, turbulence, means and methods of aero- and thermophysical experiment, physics of low-temperature plasma, and physical and technical problems of energetics. These topics are the prior fields of investigation at the Institute of Thermophysics and the Institute of Theoretical and Applied Mechanics of the Siberian Branch of the Russian Academy of Sciences (SB RAS), which are the founders of the journal along with SB RAS. This publication promotes an exchange of information between the researchers of Russia and the international scientific community.
