Particle Image Velocimetry (PIV) for Granular Avalanches on Inclined Planes
2003This paper is concerned with experimental results of sand avalanches flowing down inclined plexiglass chutes with lateral confinement. We introduce the Particle Image Velocimetry (PIV) technique for granular avalanches and discuss the differences in its implementation compared to standard PIV.

Particle Image Velocimetry (PIV) Measurements in Plunging Jets
Hydraulic Measurements and Experimental Methods 2002, 2002This 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.

Geschwindigkeitsmessungen in Kugelschüttungen mittels Particle Image Velocimetrie (PIV)
Chemie Ingenieur Technik, 2006Kugelschuttungen werden haufig in der chemischen und verfahrenstechnischen Industrie in Reaktoren oder als Trenn- oder Reinigungseinheiten eingesetzt. Genaue Kenntnisse uber die Stromung in solchen Packungen sind von grundlegendem Interesse fur die Auslegung solcher Reaktoren und fur die Vorhersage ihrer charakteristischen Eigenschaften.

Biospeckle PIV (Particle Image Velocimetry) for analyzing fluid flow
Flow Measurement and Instrumentation, 2013Abstract In this paper, we present an alternative protocol for use with the Particle Image Velocimetry (PIV) technique in fluid and particle flow monitoring, without the use of external particles seeded as targets in the cross-correlation of the flow images.

Continuously trackable PIV (particle image velocimetry) with correlation image sensor
SPIE Proceedings, 2008In this paper, we propose a new measurement scheme, called phase-stamp imaging using correlation image sensor(CIS). The correlation image sensor, developed by us, is the device which outputs the temporal correlation between incident light intensity and three reference signals which is common among whole pixel.

5th International Symposium on Particle Image Velocimetry, PIV'03
Measurement Science and Technology, 2004The advent of particle image velocimetry (PIV) in the late 20th century brought about a paradigm change in the technique of flow field measurement, from point measurement to field measurement. This revolution is a result of the recent advances in computers, video cameras, optics and lasers and a deeper understanding of the theory of image processing ...

Visualization of aerocolloidal biological particles using 2D particle image velocimetry (PIV)
SPIE Proceedings, 2003Recent concerns over the possible use of airborne biological particles as weapons of mass destruction have significantly increased the attention that researchers are giving to this threat. The size of these particles, ranging from a fraction of a micrometer to several tens of micrometers, allows them to travel over long distances before settling out ...
