Improvement in the Number of Velocity Vector Acquisitions Using an In-Picture Tracking Method for 3D3C Rainbow Particle Tracking Velocimetry

Fluids
Particle image velocimetry and particle tracking velocimetry (PTV) have developed from two-dimensional two-component (2D2C) velocity vector measurements to 3D3C measurements.

Single-camera, three-dimensional particle tracking velocimetry

Optics Express, 2012
This paper introduces single-camera, three-dimensional particle tracking velocimetry (SC3D-PTV), an image-based, single-camera technique for measuring 3-component, volumetric velocity fields in environments with limited optical access, in particular, optically accessible internal combustion engines.

Underwater LED-based Lagrangian particle tracking velocimetry

Journal of Visualization, 2022
Abstract A new white-light volumetric flow measurement technique is presented that can be used in large-scale facilities. The technique enables large volumes to be measured with high temporal and spatial resolution and without the need for a class-4 laser.

Study on visualization of water mixing flows in a digester equipped with a vertical impeller by using radiotracers

Nuclear Engineering and Technology, 2020
A mixer with a new concept design has been adapted into water treatment plants. It reportedly cuts down the energy consumption of the mixer by the new mixer, which moves vertically and creates internal flows toward its bottom.

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 retracking algorithm capable of quantifying large, local matrix deformation for traction force microscopy

PLoS ONE, 2022
Deformation measurement is a key process in traction force microscopy (TFM). Conventionally, particle image velocimetry (PIV) or correlation-based particle tracking velocimetry (cPTV) have been used for such a purpose.

Simultaneous 3D tracking and temperature measurements of L-PBF spatter particles using a single camera

Additive Manufacturing Letters, 2023
This work discusses the implementation of a novel technique for simultaneous 3D particle tracking velocimetry and dual-wavelength pyrometry of spatter particles ejected during the Laser-Powder Bed Fusion (L-PBF) process using a single high-speed spectral

Part I: 3DPTV: Advances and Error Analysis. Part II: Extension of Guderley's Solution for Converging Shock Waves [PDF]

, 2005
This work is divided into two unrelated parts. In the first part, a full three-dimensional particle tracking system was developed and tested. Three images, from three separate CCDs placed at the vertices of an equilateral triangle, permit the three ...

Objective speckle velocimetry for autonomous vehicle odometry [PDF]

, 2012
Speckle velocimetry is investigated as a means of determining odometry data with potential for application on autonomous robotic vehicles. The technique described here relies on the integration of translation measurements made by normalized cross ...
