We have investigated experimentally the twodimensional flow of stainless steel balls through a smooth inclined plane and between two parallel plates so that the side walls are rough and the inclination is adjustable. It is shown that th e dynamical behavior of the dilute granular flow is different from the Newtonian fluids because of the energy dissipation. Compared to the viscous fluids, the velocity profiles of the granular flow are more blunted than the parabolic form and the density profiles are nonuniform. Near the side walls, the density is hig her than the center of the channel. The distribution of the density is influence d by increasing inclination and the width of the channel. The transverse d istribution of the granules in the channel is affected chiefly by the density di stribution.
