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 via wavelet analysis
AIAA Journal, 1998Novel analytical and image processing methods derived as part of the development of a digital particle image velocimetry system, based on multiresolution analysis, are presented. The derivation of wavelet-based multiresolution methods for velocity e eld reconstruction is addressed, and the experimental setup used for validation of results is described.

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.

Digital Particle Image Velocimetry
2003Development of aerospace airframes and propulsion systems depends on the accurate simulation of these components in their normal operating environment. Measurement of velocity fields is of critical importance in these aerodynamic studies in order to both verify the external flow field and also to determine the performance of these components/systems in
