Abstract
The experimental study of the process of bubble detachment from a single capillary in downward liquid flow was performed. The glycerin was used as a working liquid. In order to study the effect of physical properties of liquid on the formation of bubbles experiment was conducted at different temperatures. Presented average bubble size is depended on parameters such as gas flow rate, temperature and volume velocity of liquid, as well as the capillary diameter. The data about the most characteristic mode of formation of the gas-liquid mixture was obtained. It is shown that coalescence of bubbles near the capillary is the process that determines the type of bubbles size distribution in the fluid flow. The regimes of bubble formation most suitable for the generation of a monodisperse, and bidisperse gas-liquid mixture are presented in the study.
