Microscale particle image velocimetry

Such a velocity distribution given by Eq. 31 was verified experimentally by Yan et al. [8] in which a method is proposed to simultaneously determine the zeta potentials of the channel surface and the tracer particles in aqueous solutions. This is achieved by carrying out microscale particle image velocimetry (micro-PIV) measurements of the electrokinetic velocity distributions of tracer particles in both open- and closed-end microchannels under the same water chemistry condition. 

In the following, a method will be introduced for simultaneously determining the zeta potentials of both the microchannel surfaces and the tracer particles by using the microscale particle image velocimetry (micro-PIV) technique.

Several techniques have been developed to measure the zeta potential, based on the principle of electrokinetics. In this entry, the conventional methods of measuring the zeta potential using the mechanisms of electrophoresis, streaming potential, and electroosmotic flow will be outlined first. Then, a novel method will be presented for simultaneously determining the zeta potentials of both the microchannel surfaces and the tracer particles by using the microscale particle image velocimetry (micro-PIV) technique. This method combines the theories of...

Particle based flow visualization techniques introduce marker particles into the flow field to study the motion of the bulk by determining the velocity vectors associated with these particles. Laser Doppler velocimetry (LDV), optical Doppler tomography (ODT) and particle image velocimetry (PIV) are the different methods that have been developed in this regard. However, of these methods microscale PIV ( x-PIV) is the most well-developed and popular microscale flow visualization technique.
