Application of particle image velocimetry (PIV) to vibrational finishing

Journal of Materials Processing Technology, 2016
Abstract Vibrational finishing processes are finding increased application in the finishing of high end components. Despite the growing popularity of vibrational finishing, and due to limited suitable process instrumentation, understanding of underlying physical processes remains largely anecdotal and empirical, and system-independent process control

Fundamentals of multiframe particle image velocimetry (PIV)

Experiments in Fluids, 2007
A sophisticated strategy for the evaluation of time-resolved PIV image sequences is presented which takes the temporal variation of the particle image pattern into account. The primary aim of the method is to increase the accuracy and dynamic range by locally adopting the particle image displacement for each interrogation window to overcome the largest

Particle image velocimetry (PIV) analysis of flame structure

Journal of Loss Prevention in the Process Industries, 2001
Abstract An experimental study of methane–air flame propagation in a duct is reported. A flat duct was chosen to allow optical visualization and flame propagation measurements. The duct was equipped with optical-quality windows to allow Schlieren visualization and particle image velocimetry (PIV) velocity measurements. The flame propagation velocity,

Particle Image Velocimetry (PIV) Measurements in Plunging Jets

Hydraulic Measurements and Experimental Methods 2002, 2002
This paper presents the research performed to define the current abilities and limits of PIV in measuring air concentration and velocity in spillway plunging jets. The research concluded that PIV measurement methods can successfully measure velocity and air concentration in a stilling basin environment.

Performance comparison of particle tracking velocimetry (PTV) and particle image velocimetry (PIV) with long-exposure particle streaks

Measurement Science and Technology, 2020
Abstract Particle tracking velocimetry (PTV) and particle image velocimetry (PIV) are popular experimental methods to quantitatively measure flow fields. In many practical applications, hardware limitations result in longer exposure times, causing particle images to elongate into particle streak images.
