Phys. Rev. E 65, 061303 (2002) [20 pages]Continuum theory of partially fluidized granular flowsReceived 19 September 2001; revised 18 January 2002; published 21 June 2002 A continuum theory of partially fluidized granular flows is developed. The theory is based on a combination of the equations for the flow velocity and shear stresses coupled with the order-parameter equation which describes the transition between the flowing and static components of the granular system. We apply this theory to several important granular problems: avalanche flow in deep and shallow inclined layers, rotating drums, and shear granular flows between two plates. We carry out quantitative comparisons between the theory and experiment. © 2002 The American Physical Society URL:
