Granular flow is a form of two-phase flow consisting of particles and interstitial fluid. When sheared, the particulates may either flow in a manner similar to a fluid or resist the shearing like a solid. The dual nature of these types of flows makes them difficult to analyze. There is no deterministic description of the granular flow behavior unless it is approximated by the laws governing

10/01/1997 Material flow in partially filled rotating cylinders (rotary kilns) is encountered in many practical applications of material processing, for example incineration, calcination, grain drying, etc. The flow behaviour 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 which was
