Developing Tracer Particles for X-Ray Particle Tracking Velocimetry

open access: yesASME-JSME-KSME 2011 Joint Fluids Engineering Conference: Volume 1, Symposia – Parts A, B, C, and D, 2011
X-ray imaging, as a noninvasive flow visualization technique, has been shown to be a useful method for observing and characterizing multiphase flows. One type of X-ray flow visualization technique, called X-ray Particle Tracking Velocimetry (XPTV), tracks an X-ray attenuating particle in an opaque fluid flow.

Machine learning enhanced time-resolved multi-particle tracking velocimetry in solid fuel particle group combustion

open access: yesApplications in Energy and Combustion Science
Particle velocity is an essential parameter in solid fuel combustion studies, however, the accurate detection and tracking of particles in high particle number density (PND) combustion scenario remain challenging.

Geometrical statistics of the vorticity vector and the strain rate tensor in rotating turbulence

open access: yes, 2013
We report results on the geometrical statistics of the vorticity vector obtained from experiments in electromagnetically forced rotating turbulence. A range of rotation rates $\Omega$ is considered, from non-rotating to rapidly rotating turbulence with a

High-precision and high-accuracy stereophotogrammetric image analysis for small to large strain deformation measurement in triaxial apparatus [PDF]

open access: yesE3S Web of Conferences
A deformation measurement system for laboratory soil testing based on stereophotogrammetric image analysis was developed with a purpose of characterising soil behaviour continuously from small to large strains.

Particle Cluster Tracking Algorithm in Particle Image Velocimetry.

open access: yesJSME International Journal Series B, 1998
The cross-correlation tracking technique is widely used to analyze image data, in particle image velocimetry(PIV). The technique assumes that the fluid motion, within small regions of the flow field, is parallel over short time intervals. However, actual flow fields may have some distorted motion, such as rotation, shear and expansion.

Analysis of turbulence and vortex structures by flow mapping [PDF]

open access: yes, 1997
The technique of Particle Image Velocimetry (PIV) flow mapping is reviewed and comparisons made with Laser Doppler Anemometry (LDA). Results are presented showing the application of PlV to the determination of coherent structures in grid-generated ...
