Abstract

A granular material is a collection of a large number of discrete solid particles with interstices filled with a fluid or a gas. If the interstitial fluid plays an insignificant role in the transportation of momentum, flows of such materials can be considered as dispersed single-phase flows. In other occasions, when the mass of the interstitial fluid is comparable to that of the solids the interactions between the fluid and solid phases are significant, the motion of the fluid can then provide the driving force for the flow of the solid phase. The dynamical behaviour of these materials can be very complex; its description involves aspects of traditional fluid mechanics, plasticity theory, soil mechanics and rheology.
