Functionalised alginate flow seeding microparticles for use in Particle Image Velocimetry (PIV).
TL;DR: The performances of alginate microparticles functionalised with a fluorescent dye, Rhodamine B (RhB), for PIV have been studied and the efficacy of fluorescence is appreciated in a number of PIV applications since it can boost the signal-to-noise ratio.

Two-phase flow structure at header-channel junctions : PIV experiments and modeling
TL;DR: In this paper, a theoretical analysis for the onset of gas entrainment in a single downward discharge, from a stratified gas-liquid region, was developed, where the discharge was modeled as a point-sink and Kelvin-Laplace's equation was used to incorporate surface tension effects.

Particle Image Velocimetry: A Practical Guide
TL;DR: In this paper, the authors present a practical guide for the planning, performance and understanding of experiments employing the PIV technique, which is primarily intended for engineers, scientists and students, who already have some basic knowledge of fluid mechanics and nonintrusive optical measurement techniques.

Digital Particle Image Velocimetry
Christian Willert,Morteza Gharib +1 more
TL;DR: In this article, the directional ambiguity associated with PIV and LSV is resolved by implementing local spatial cross-correlations between two sequential single-exposed particle images, and the recovered velocity data are used to compute the spatial and temporal vorticity distribution and the circulation of the vortex ring.

Fundamentals of digital particle image velocimetry
TL;DR: In this paper, the measurement principle of digital particle image velocimetry (PIV) is described in terms of linear system theory and conditions for PIV correlation analysis as a valid interrogation method are determined.
