Speeds of free emersion of bubbles (the viscous mode of emersion) are investigated, at emersion of bubbles as quasifi rm sphere under Stokess law. Emersion speeds at deformations of bubbles from spherical to griboobrazny are considered; at the square law of resistance of emersion of large bubbles, at the slow expiration of gas in the landlocked volume of liquid from an opening. Infl uence of geometry of channels on the speed of emersion of bubbles is analyzed. For processing of experimental data semi-empirical methods of the theory of similarity are used.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
