Abstract

Generally, droplet velocity in liquid-liquid two-phase flow in microchannel is obtained via droplet displacement and time interval precise determination in sequential photos/videos. The precision is tightly related to shutter speed of the camera. In this paper, a novel method called direct image method is proposed to predict the droplet velocity. The droplet velocity can be easily obtained in one snapshot by this method. In order to validate the accuracy of this novel method, experiments are carried out in water-butanol, water-hexane and water-oil (Mogul Trafo CZ-A Paramo) systems. The droplet velocity predicted by this direct image method shows a good agreement with the experimental data. Although the assumptions which has been used to... (More)

The droplet velocity can be easily obtained in one snapshot by this method. In order to validate the accuracy of this novel method, experiments are carried out in water-butanol, water-hexane and water-oil (Mogul Trafo CZ-A Paramo) systems. The droplet velocity predicted by this direct image method shows a good agreement with the experimental data. Although the assumptions which has been used to determine the droplet velocity still need to be improved, this method can be useful in industrial application.
