Particle image velocimetry(PIV) is an experimental tool in fluid mechanics and aerodynamics. The basic principle involves photographic recording of the motion of microscopic particles that follow the fluid or gas flow. Image processing methods are then used to determine the particle motion, and hence ...
Particle image velocimetry (PIV) is a widely used technique for measuring velocity fields [1,2]. With volumetric PIV measurement, complex flows can be investigated regarding their three-dimensional three-component (3D3C) flow structures. Among all the 3D3C measurement methods, tomographic PIV (Tomo...
Particle Image Velocimetry (PIV) is a new technique which provides an instantaneous velocity profile of a flow field. A PIV system at Edinburgh University has been adapted to study the phenomenon of roping in a pneumatic particle conveyance rig. The principle features of this PIV system are as ...

In this study a review is carried out on the advanced use of Particle Image Velocimetry Analysis (PIV Analysis) and Digital Image Correlation Techniques (DIC Techniques), to a series of physical model tests performed over the last 5 years. Several dry and semi-submerged scaled slope models have...
Stereoscopic particle image velocimetry (PIV) employs two cameras to record simultaneous but distinct off-axis views of the same region of interest (illuminated plane within a flow seeded with tracer particles). Sufficient information is contained in the two views to extract the out-of-plane motion...
In particle image velocimetry applications involving either low velocities or small seed particles, Brownian motion can be significant. This paper addresses the effects of Brownian motion. First, general equations describing cross-correlation particle image velocimetry are derived that include Brownian motion...
