A New Particle Extraction Algorithm for Particle Tracking Velocimetry.
Journal of the Visualization Society of Japan, 2000 A new method of particle image detection has been implemented and tested for the use in the particle tracking velocimetry. The method benefits from a new algorithm of extracting individual particle images from a massive concentration of particles recorded in the PIV recordings.

Predictions of Particle Trajectory Response to Reynolds Number in Turbulent Channel Flows Using ANNs
Chemical Engineering &Technology, Volume 49, Issue 4, April 2026.A hybrid machine‐learning framework is developed to predict statistical particle trajectories in turbulent channel flows. Trained on direct numerical simulation and Lagrangian particle tracking data, the model is shown to accurately reproduce velocity statistics and concentration profiles while generalizing across Reynolds numbers, offering a reduced ...
