The behaviour of granular material in motion is studied from a continuum point of view. Insofar as possible, individual grains are treated as the 'molecules' of a granular 'fluid'. Besides the obvious contrast in shape, size and mass, a key difference between true molecules and grains is that collisions of the latter are inevitably inelastic. This, together with the fact that the fluctuation velocity may be comparable to the flow velocity, necessitates explicit incorporation of the energy… CONTINUE READING
