This work consists of an experimental analysis of the liquid-liquid two-phase flow of water-kerosene through a vertical bend. The duct has diameter of 0.026 m, the bend radius is 0.125 m and the superficial velocities of the water and kerosene ranged from 0.1 to 1.0 m/s. The pressures drops were measured by differential pressure transducers SMAR LD301, the holdups were determined by the method of trapping fluid using quick-closing valves and the flow patterns was determined using a high-speed camera. The bend pressure gradient is increased with the superficial velocities of both phases. The bend coefficient has no correlation with the mixture Reynolds number, such as in single-flows. The modified Reynolds number proposed by [1] described accurately the bend flow pattern.
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.
