Particle Image Velocimetry (PIV) belongs to the class of optical “whole- field” measuring techniques. The name of the method is self-explaining: The velocity distribution in a whole field of a fluid flow is determined by measuring the displacements Δs that the images of tracer particles experience during a time interval Δt.

Thermographic Particle Image Velocimetry
Imaging and Applied Optics 2014, 2014Planar high-speed temperature and velocity measurements in gaseous flows can be performed simultaneously using micrometer-sized thermographic phosphor particles as tracers. Validation of this concept and applications in turbulent flows will be presented.

Photogrammetric Particle Image Velocimetry
2004The Particle-Image Velocimetry (PIV) is a meanwhile quite mature measuring method in its application on a 2-dimensional (2D) measuring plane for the collection of 2 or 3 velocity-components (2C resp. 3C) within this plane (planar PIV). A disadvantage is the limitation to a plane of 1...5 mm thickness.

Particle Image Velocimetry by Feature Tracking
2001Particle Image Velocimetry (PIV) is a popular approach to flow visualisation in hydro- and aerodynamic studies and applications. The fluid is seeded with particles that follow the flow and make it visible. Traditionally, correlation techniques have been used to estimate the displacements of the particles in a digital PIV sequence.

Stereoscopic particle image velocimetry
Experiments in Fluids, 2000Stereoscopic 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 of particles, and also to eliminate perspective error ...

Thermographic Particle Image Velocimetry
Renewable Energy and the Environment, 2013The particle image velocimetry technique can be extended to simultaneously measure fluid temperatures by seeding thermographic phosphor particles. Following UV excitation, these particles exhibit a temperature-dependent phosphorescence spectrum that can be utilized for thermometry.
