Astigmatism Particle Tracking Velocimetry for Macroscopic Flows

, 2013
Astigmatism Particle Tracking Velocimetry (APTV) is a three-dimensional flow measurement technique. It requires only a single camera and is therefore best suited for measurement domains with limited optical access, such as compressor and combustion ...

D Particle Tracking Velocimetry Based On

, 2002
The 3D Particle Tracking Velocimetry (PTV) offers a flexible technique for the determination of velocity fields in flows. In the past decade the successful research work performed by the Institute of Geodesy and Photogrammetry at ETH Zurich led to an ...

Coherent structures and bubble-particle velocity in 2-D fluidized beds [PDF]

, 2008
This work presents an experimental study to characterize ascending bubbles and granular velocity in the dense phase of a 2-D fluidized bed. Three different non-intrusive techniques based on images obtained with a high speed camera are developed, and ...

Tomographic X-ray particle tracking velocimetry

, 2022
Abstract: We investigate the feasibility of in-laboratory tomographic X-ray particle tracking velocimetry (TXPTV) and consider creeping flows with nearly density matched flow tracers. Specifically, in these proof-of-concept experiments we examined a Poiseuille flow, flow through porous media and a multiphase flow with a Taylor bubble.
