Recent Advances in Micro-Particle Image Velocimetry

Microfluidic devices are becoming increasingly common and are seen in applications ranging from biology to nanotechnology and manufacturing. Flow behavior in these small domains can often be counterintuitive because of the low Reynolds number or the relative importance of surface forces. Microparticle image velocimetry (μPIV) is a quantitative method that can be used to characterize the perform...

3 D Particle Tracking Velocimetry Method : Advances and Error Analysis

A full three-dimensional particle tracking system was developed and tested. By using three separate CCDs placed at the vertices of an equilateral triangle, the threedimensional location of particles can be determined. Particle locations measured at two different times can then be used to create a three-component, three-dimensional velocity field. Key developments are: the ability to accurately ...

Recent Advances in Adaptive Particle Swarm Optimization Algorithms

This paper reviews recent literature on the mechanisms for adapting parameters of particle swarm optimization (PSO) algorithm. The review covers the mechanisms for adaptively setting such parameters as inertia weight, acceleration constants, number of particles and number of iterations. In additions, a more thorough review of the mechanisms for adapting inertia weight and acceleration constants...
