Comparison of PIV measurements and a discrete particle model in a rectangular 3D spout-fluid bed [PDF]
, 2004 Particle image velocimetry and a 3D hard sphere discrete particle model were applied to determine particle velocity profiles in the plane around a spout in a spoutfluid bed for various initial bed heights, spout and background fluidization velocities ...

Echo Particle Image Velocimetry [PDF]
Journal of Visualized Experiments, 2012 The transport of mass, momentum, and energy in fluid flows is ultimately determined by spatiotemporal distributions of the fluid velocity field.(1) Consequently, a prerequisite for understanding, predicting, and controlling fluid flows is the capability to measure the velocity field with adequate spatial and temporal resolution.(2) For velocity ...

Particle Imaging Velocimetry Gyroscope [PDF]
Sensors, 2019 Inertial measurement units (IMUs) are typically classified as per the performance of the gyroscopes within each system. Consequently, it is critical for a system to have a low bias instability to have better performance. Nonetheless, there is no IMU available commercially that does not actually suffer from bias-instability, even for the navigation ...

Performance prediction of point-based three-dimensional volumetric measurement systems [PDF]
, 2008 Point-based three-dimensional volumetric measurement systems are defined as multi-view vision systems which reconstruct a three-dimensional scene by first identifying key points on the views and then performing the reconstruction.

Particle image velocimetry studies of bubble growth and detachment by high speed photography [PDF]
, 1997 An understanding of bubble flows is important in the design of process equipment, particularly in the chemical and power industries. In vapour-liquid processes the mass and heat transfer between the phases is dominated by the liquid-vapour interface and ...

Defocusing digital particle image velocimetry and the three-dimensional characterization of two-phase flows [PDF]
, 2002 Defocusing digital particle image velocimetry (DDPIV) is the natural extension of planar PIV techniques to the third spatial dimension. In this paper we give details of the defocusing optical concept by which scalar and vector information can be ...

Digital particle image velocimetry [PDF]
Experiments in Fluids, 1991 Digital particle image velocimetry (DPIV) is the digital counterpart of conventional laser speckle velocitmetry (LSV) and particle image velocimetry (PIV) techniques. In this novel, two-dimensional technique, digitally recorded video images are analyzed computationally, removing both the photographic and opto-mechanical processing steps inherent to PIV

Meta-uncertainty for particle image velocimetry [PDF]
Measurement Science and Technology, 2021 Abstract Uncertainty quantification for particle image velocimetry (PIV) is critical for comparing experimentally measured flow fields with computational fluid dynamics results, and model design and validation. However, PIV features a complex measurement chain with coupled, non-linear error sources, and quantifying the uncertainty is ...
