We investigate the bulk rheology of dense granular flow down a rough slope,where the density profile has been found to show a plateau except for theboundary layers in simulations [Silbert {\it et al.}, Phys. Rev. E {\bf 64},051302 (2001)]. It is demonstrated that both the Bagnold scaling and theframework of kinetic theory are applicable in the bulk, which allows us toextract the constitutive relations from simulation data. The detailedcomparison of our data with the kinetic theory shows quantitative agreement forthe normal and shear stresses, but there exists slight discrepancy in theenergy dissipation, which causes rather large disagreement in the kinetictheory analysis of the flow.Comment: 4 pages, 3 figures.
