Tomographic particle image velocimetry
Experiments in Fluids, 2006This paper describes the principles of a novel 3D PIV system based on the illumination, recording and reconstruction of tracer particles within a 3D measurement volume. The technique makes use of several simultaneous views of the illuminated particles and their 3D reconstruction as a light intensity distribution by means of optical tomography.

Time-resolved particle image velocimetry
Measurement science and technology, 2021Time-resolved particle image velocimetry (TR-PIV) has become widespread in fluid dynamics. Essentially a velocity field movie, the dynamic content provides temporal as well as spatial information, in contrast to conventional PIV offering only statistical

Deformed Particle Image Pattern Matching in Particle Image Velocimetry
Applied Scientific Research, 1993The deformation of particle image patterns due to velocity gradients causes errors of velocity measurements and false velocity detections in PIV (Particle Image Velocimetry). A novel technique to overcome those limitations inherent in the conventional PIV by correcting the particle image pattern according to the local velocity gradients in two ...

Particle image velocimetry (PIV), also called particle image displacement velocimetry (PIDV), is a method of whole flow field velocimetry, which is currently causing a lot of interest. This methodrelies on the recording of particle positions in a section of the flow at a given instant in time. The measurement region may be defined by a thin laser sheet

Moving fluids have always been an object of fundamental physical research. An understanding of the dynamic behavior of streaming liquids and gases is the basis for disciplines in engineering ranging from the design of aircraft and ships to harbor development, wavebreaker projects, cavitation erosion, or sound production and attenuation.

Electrooptical image shifting for particle image velocimetry
Applied Optics, 1988The direction of fluid motion can be determined in particle image velocimetry (and laser speckle velocimetry) if the image field is spatially shifted between the first and second exposures, so that the most negative fluid velocity still produces a positive particle image displacement. Two new techniques are described which accomplish very fast accurate

Particle image and tracking velocimetry of solid-liquid turbulence in a horizontal channel flow
International Journal of Multiphase Flow, 2019The turbulence statistics of the solid and liquid phases in a horizontal turbulent channel flow are experimentally investigated to identify the effect of particle size, flow Reynolds number (Re) and the volumetric concentration of particles.
