In this review we discuss the state of the art of the optical whole-field velocity measurement
technique micro-scale Particle Image Velocimetry (µPIV). µPIV is a useful tool for …

The reliable measurement of the 3D3C velocity field in microfluidic devices becomes more
and more important for future optimization and developments for lab-on-a-chip applications …

High-powered light emitting diodes (LED) are investigated for possible uses as light sources
in flow diagnostics, in particular, as an alternative to laser-based illumination in particle …

Light-emitting diodes (LEDs) are playing increasingly important roles in analytical chemistry,
from the final analysis stage to photoreactors for analyte conversion to actual fabrication of …

A visualization experiment was conducted to investigate the electrohydrodynamic
deformation of droplets in a combined DC electric field and shear flow field. Detailed …

The hydrodynamic characteristics of liquid-liquid plug flow were studied in microchannels
with 0.2 and 0.5 mm ID both experimentally and numerically. For the experiments high …

We demonstrate the viability of using four low-cost smartphone cameras to perform
Tomographic PIV. We use colored shadows to imprint two or three different time-steps on the …

A simple experimental setup to study the impact and coalescence of deposited droplets is
described. Droplet impact and coalescence have been investigated by high-speed particle …

This review article focuses on the simultaneous particle-based measurement of velocity and
temperature. The thermographic PIV with phosphor particles is included in the scope …

This paper investigates the use of high-power light-emitting diode (LED) illumination for
tomographic particle image velocimetry (PIV) as an alternative to traditional laser-based …
