We investigate Particle Image Velocimetry and its applications to analyzing granular media. To apply PIV to our experiments in granular media we will be using PIVLab developed by William Thielicke and Eize J. Stamhuis. An overview of the program will be given along with the process of image analyses that was used. Using 5mm spherical beads as our granular media we will pass intruders of various diameters through the granular material at varying immersion depths and velocities in order to create granular flow. Recording videos of these experiments and processing them with PIVLab we will attempt to show that the shearing and pileup regions in the granular flow are independent of velocity. PIVLab will also be used to investigate areas of surface vorticity in the granular flow.
