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

An advanced laser-Doppler velocimeter for full-vector particle position and velocity measurements
K T Lowe,Roger L. Simpson +1 more
TL;DR: In this article, an advanced laser-Doppler measurement technique has been developed for fully resolved three-component particle position and velocity vector measurements in turbulent flows, which allows for velocity statistics measurements at multiple locations within the measurement volume.

The relative stability of salmon redds and unspawned streambeds
Todd H. Buxton,Todd H. Buxton,John M. Buffington,Elowyn M. Yager,Marwan A. Hassan,Alexander K. Fremier +5 more
TL;DR: In this paper, the relative stability of completed nests and unspawned beds was investigated in flume experiments where redds were constructed with a technique that mimics the nesting behavior of female salmon.

Split-screen single-camera stereoscopic PIV application to a turbulent confined swirling layer with free surface
TL;DR: In this paper, an annular liquid wall jet, or vortex tube, generated by helical injection inside a tube is studied experimentally as a possible means of fusion reactor shielding, and a split-screen, single-camera ste- reoscopic particle image velocimetry (SPIV) scheme is employed for flow field characterization.

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.
