Twenty years of particle image velocimetry
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

The effect of geometry on ice shelf ocean cavity ventilation: a laboratory experiment
TL;DR: In this paper, a laboratory experiment is constructed to simulate the density-driven circulation under an idealized Antarctic ice shelf and to investigate the flux of dense and freshwater in and out of the ice shelf cavity.
Stochastic Surrogates for Measurements and Computer Models of Fluids
TL;DR: A general framework that uses a stochastic surrogate to address the prediction problem of Computational Fluid Dynamics, derived in a Bayesian framework, and provides analytical estimates for conditions under which the Kriging predictor is robust.
Dissertation
Landslide recognition and monitoring with remotely sensed data from passive optical sensors
TL;DR: In this paper, the authors developed and applied image processing techniques for the mapping, characterisation and monitoring of landslides with optical remote sensing data, and showed the potential and limitations of available techniques and guided the selection of the most appropriate combination of sensors.

Fluidics of Single and Double Blade Guillotine Vitrectomy Probes in Balanced Salt Solution and Artificial Vitreous.
TL;DR: The DB has more efficient fluidics than SB vitrectomy probe in all tested conditions and its cutters prove to be more efficient in terms of lower acceleration for a given flow rate.

Comparison of the aerosol velocity of Respimat soft mist inhaler and seven pressurized metered dose inhalers
TL;DR: The aerosol spray velocities of seven pMDIs containing hydrofluoroalkane (HFA) propellant and one Respimat SMI were measured using particle image velocimetry2 (PIV), a wellestablished method in fluid dynamics.

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.

Particle Image Velocimetry
TL;DR: In this paper, the authors use hot-wire (HW) or laser velocimetry (LV) to estimate the velocity, vorticity, and pressure fields of wake flows.

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.
