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 model is extended to build a master curve that can be used for predicting the interfacial tension. The models and master curves are obtained based on experimental data for gas-phase motion through the interface between immiscible liquids, which makes the modeling results more reliable for gas-liquid-liquid systems.

通过不混溶液体界面上升气泡的夹带主曲线预测界面张力

液-液界面张力是气-液-液多相流中的一个重要参数。在这里，通过不混溶液体界面的气泡通道用于确定界面张力。该方法基于测量夹带到轻液体中的重液体的体积。开发了两种不同的半经验模型来确定夹带率。结果与涵盖各种液体物理性质的实验非常吻合。扩展每个模型以构建可用于预测界面张力的主曲线。模型和主曲线是基于气相运动通过不混溶液体之间界面的实验数据获得的，这使得气-液-液系统的建模结果更加可靠。
