Abstract:Liquid‐liquid interfacial tension is an important parameter in gas‐liquid‐liquid multiphase flows. Here, bubble passage through an immiscible liquids interface was used for determining the interfacial tension. The method is based on measuring the volume of the heavy liquid entrained into the light one. Two different semi‐empirical models were developed for determining the entrainment ratio. The results are in good agreement with experiments covering a wide range of physical properties of the liquids. Each mode… Show more
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.
