Abstract

Although the phenomena related to the multiphase flow can be found in many kinds of industrial and engineering applications, the physical mechanism of the multiphase flow has not been investigated in detail. The major reason for the lack of data in the multiphase flow lies in the difficulties in measuring the flow quantities of the multiple phases simultaneously. The difference in the refractive indices makes the visualization almost impossible. The authors of this study have developed the technique for the simultaneous visualization of the both phases of the liquid-liquid two-phase flow by adjusting the refractive indices of both phases. In this study, the PIV measurement has been carried out for a water droplet falling near the wall in the stationary oil. The results reveal the typical features of the effect of the wall on the convection around and inside of a droplet.
