The implementation of PIV for experimental studies in open-channel flows can be
challenging due to the presence of strong velocity gradients and the inclusion of solid …

The spatial resolution of PIV can be increased significantly by using an image deformation
method (IDM) and very small grid distance (ie the final distance between vectors), therefore …

Digital image correlation (DIC), also known as particle image velocimetry (PIV), has become
a well-established approach for the calculation of field displacements in geotechnical …

A novel laboratory experiment for investigating statistically steady rotating turbulence is
presented. Turbulence is produced nonintrusively by means of electromagnetic forcing …

In this paper, algorithms to describe mesoscale and microscale kinematics of granular flow
using image analysis are described. At the mesoscale, digital image correlation (DIC) is …
