Image separation and reconstruction for simultaneous measurement of multi-velocity field

Simultaneous measurement of the dynamic motion of each phase in dense multiphase flow is very important to understand physically the structures of the multiphase flow. A flow visualization measurement method based on the image separation and reconstruction is proposed to measure multiple velocity fields from single-camera images. The method extends conventional PIV/PTV to measure simultaneously the flow fields of the each phase with a high accuracy in the present study. The technique have wide practical application in industrial processes.
