| Contact properties in flowing granular media are significant for simulations of granular flows. Material flow in partially filled rotating cylinders is encountered in many practical applications of material processing, for example incineration, calcinations, grain drying, etc. The flow behavior in the cross-section is important to other transport mechanisms such as mixing and energy distribution within the bed material. The paper describes an experimental study that was carried out with the objective of understanding the loss of energy in the rolling cylinder due to frictional and restitution properties of the grains. It shows how a cylinder with different type of granular material filling with varying level of filling can bring change in momentum of the cylinder while rolling over a ramp. |
