Abstract
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. Presently, the simultaneous visualization has been carried out about the both phases of the liquid-liquid two-phase flow by adjusting the refractive indices of both phases. The PIV measurement has been carried out for a falling water droplet near the wall in the stationary oil. The results reveal the typical features of the effect on the convection around and inside of a droplet.
