Investigation of the hydrodynamic behaviour of particles and aggregates by particle image velocimetry (PIV) [PDF]
Water Science and Technology: Water Supply, 2007 An advanced fluid visualisation technique, particle image velocimetry, was employed to investigate the hydrodynamic properties of particles and aggregates. The experiments were conducted in a settling column filled with a suspension of fluorescent polymeric beads as flow tracers. A thin vertical section of the settling column was illuminated by a laser

Particle Image Velocimetry Algorithm Based on Spike Camera Adaptive Integration [PDF]
SensorsIn particle image velocimetry (PIV), overexposure is particularly common in regions with high illumination. In particular, strong scattering or background reflection at the liquid–gas interface will make the overexposure phenomenon more obvious ...

A Novel Polynomial Approach for Particle Image Velocimetry (PIV) Image Reconstruction
FluidsParticle Image Velocimetry (PIV) often utilizes a cross-correlation method to determine how far particles have moved between two captured images. The most common methods for vector estimation use computationally exhaustive cross-correlation functions ...

Grid turbulence studied by Particle Image Velocimetry [PDF]
EPJ Web of Conferences, 2022 We studied the grid-generated turbulence by using Particle Image Velocimetry (PIV) technique. We test on this already well studied flow the new ways of analyzing spatially resolved PIV data, such as the spatial spectra and structure functions. We compare
