This paper presents a microfluidic approach that dynamically controls the hydrodynamic flow and the streamlines to enable complex multi-particle manipulations within a single device. The approach combines the design of a flow-through microfluidic Hele-Shaw flow cell together with ...

Ψ -PIV

A novel framework to study unsteady microfluidic flows

Abstract: In microscopic particle image velocimetry (micro-PIV), correlation averaging over multiple frames is often required, leading to a loss in temporal resolution, therefore limiting the measurement accuracy for unsteady flows. Here, we present a new PIV method suitable to s ...
In micro-PIV, reaching the optimum image density has always been difficult due to high displacement gradient, coagulation of particles at the inlet and due to particles adhering to the surface to name a few. The most widely used method is to take ensemble correlation average of m ...
