Experimental characterization of solid particle transport by slug flow using Particle Image Velocimetry

This paper presents an experimental study of gas-liquid slug flow on solid particle transport inside a horizontal pipe with two types of experiments conducted. The influence of slug length on solid particle transportation is characterized using high speed photography. Using combined Particle Image Velocimetry (PIV) with Refractive Index Matching (RIM) and fluorescent tracers (two-phase oil-air ...

Particle migration in pressure-driven flow of a Brownian suspension

Shear induced particle migration of 2 μm diameter spherical colloidal particles flowing through rectangular capillary tubes (50 μm × 500 μm cross section) is studied by confocal microscopy. The confocal microscope allows imaging of the flowing particles far from the walls of the tube, at particle velocities up to 8000 μm s−1. The particle volume fraction is varied from φ = 0.05–0.34, and the fl...

Using optical flow equation for particle detection and velocity prediction in particle tracking

A new algorithm of particle identification suitable for particle tracking technique in fluid mechanics is proposed and tested with synthetic images specifically developed with different particle parameters. The new approach is based on the solution of the optical flow equation via a sum-of-squared-difference method. Particles are detected through the identification of corner features, where ima...
