TLDR
The development of the method of particle image velocimetry (PIV) is traced by describing some of the milestones that have enabled new and/or better measurements to be made.Abstract:
The development of the method of particle image velocimetry (PIV) is traced by describing some of the milestones that have enabled new and/or better measurements to be made. The current status of PIV is summarized, and some goals for future advances are addressed.read more

Wall build up in spray dryers
TL;DR: In this article, wall deposition was broken down into two critical steps; collision frequency, describing how many and how often particles hit the wall and, collision success rate which describes particle's behaviour upon contact with the wall.

Large-Scale Particle Image Velocimetry to Measure Streamflow from Videos Recorded from Unmanned Aerial Vehicle and Fixed Imaging System
TL;DR: In this article, the authors measured surface velocities collected under low flow and high flow conditions in the Houlong River, Taiwan, using large-scale particle image velocimetry (LSPIV) captured by an unmanned aerial vehicle (UAV) and a terrestrial fixed station.

An Experimental Investigation of the Liquid Flow Induced by a Pulsed Electrical Discharge Plasma
TL;DR: In this paper, particle image velocimetry has been used to visualize and quantify plasma-induced flow fields in liquid water, and the velocity field has been quantified for two types of solutions: (1) aqueous NaCl solutions of varying solution conductivities and discharge frequencies, and (2) NaCl solution containing varying concentrations of the following four organic compounds: rhodamine B dye, caffeine, fluoxetine, and perfluorooctanoic acid.

Laminar mixing using oscillating cantilevered ionic polymer actuators
TL;DR: In this paper, a novel active mixing device for laminar flows was developed using Nafion-based Ionic Polymer Transducers (IPTs), which are a class of active materials that are thin, flexible, inexpensive, readily deployable in an aqueous medium, and offer strains up to 10% under a small (

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.

Determination of displacements using an improved digital correlation method
TL;DR: An improved digital correlation method is presented for obtaining the full-field in-plane deformations of an object by numerically correlating a selected subset from the digitized intensity pattern of the undeformed object.

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.
