Particle Image Velocimetry Algorithm Based on Spike Camera Adaptive Integration [PDF]

open access: yesSensors
In 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 ...

Digital particle image velocimetry [PDF]

open access: yesExperiments in Fluids, 1991
Digital particle image velocimetry (DPIV) is the digital counterpart of conventional laser speckle velocitmetry (LSV) and particle image velocimetry (PIV) techniques. In this novel, two-dimensional technique, digitally recorded video images are analyzed computationally, removing both the photographic and opto-mechanical processing steps inherent to PIV

Grid turbulence studied by Particle Image Velocimetry [PDF]

open access: yesEPJ 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
