Characterization of flocs in coagulation processes in Taylor-Couette flow by PIV

摘要：

　　Particle image velocimetry (PIV) was applied to characterize the morphological changes of flocs and to acquired velocity field data in the coagulation process in Taylor-Couette reactor.By use of PIV,the morphological of the flocs in the coagulation process can be characterized and described with good performance.It was shown that the flocculation efficiencies reached the maximum values and the size of the generated flocs in the coagulation process was the biggest when the roating speed was in the range between 20~ 60 rpm.It was demonstrated that PIV can be exploited as a useful tool in the in-situ observation flocs during coagulation processes.
