Neural Particle Image Velocimetry
CoRR, 2021 In the past decades, great progress has been made in the field of optical and particle-based measurement techniques for experimental analysis of fluid flows. Particle Image Velocimetry (PIV) technique is widely used to identify flow parameters from time-consecutive snapshots of particles injected into the fluid.

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 ...

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 ...

Considerations When Applying Large-Scale PIV and PTV for Determining River Flow Velocity
Frontiers in Water, 2021 Large-scale image velocimetry is a novel approach for non-contact remote sensing of flow in rivers. Research within this topic has largely focussed on developing specific aspects of the image velocimetry work-flow, or alternatively, testing specific ...

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 ...

Adaptive particle image velocimetry based on sharpness metrics
Journal of the European Optical Society-Rapid Publications, 2018 Background Optical distortions can significantly deteriorate the measurement accuracy in particle image velocimetry systems. Such distortions can occur at fluctuating phase boundaries during flow measurement and result from the accompanied refractive ...
