Discussion the Method of the Flocculation Flow Field Measurement by PIV

Abstract:

Particle image velocimetry was applied to measure the velocity field during the flocculation process under the conditions that the flocs compounded with kaolin and polyaluminium chloride were used as seed particles without any other special seed particle during the flocculation process. The results indicated that the flocs formed in the flocculation process can be used as seed particles to measure the instantaneous velocity maps of the flow field with good performance during the flocculation process by PIV. At the same time, the experimental results proved that PIV can be exploited as a useful tool in the synchronism measurement the velocity field and flocculation processes.
