Abstract
We consider an inclined flow of two different types of spheres in which there is a dense collisional flow above a layered flow that involves force-chains that extend through its depth. In the latter, the granular temperature increases linearly from its base, in the former the granular temperature increases linearly from its top. Consequently, for spheres of the same material, the larger spheres segregate away from the point of transition between the flows and towards the bottom of the layered flow and the top of the collisional flow. The concentration profiles for spheres made of different materials exhibit more complicated behaviour, depending on the ratios of mass and size.
