Abstract

Flowing granular materials do not behave like liquids. The origins of these differences are related to the dissipation of energy in the system, which is linked to the grains being macroscopic particles. By examining velocity profiles of granular flow this thesis attempts to determine what parameters can affect the shear zones near the edges of the flow. Hopper width and flow speed are found to have no effect on the shear zones, while packing structure causes a significant change. Fluctuations in velocity are also measured and are found to be inversely related to the velocity profile.
