Granular phenomena are observed in a variety of industries, including the energy sector. Biofuel in the form of pellets made of compressed agricultural residue provides a clean form of renewable energy. The energy-intense transportation of these pellets reduces efficiencies.;This thesis explores biofuel transport using an aluminum oxide analogue in a flighted conveyor with a flow-limiting aperture. First, a review of granular phenomena is presented, followed by a brief overview of current experimental methods. Next, new methods of analysis are introduced, and flow is measured as aperture size and conveyor speed are varied. Finally, the conclusion is drawn that mass flux decreases linearly with an increase in Bagnold number magnitude, and efficacy increases exponentially as a function of Bagnold number.
