Force and torque acting on particles in a transitionally rough open channel flow

open access: yes, 2011
Direct numerical simulation of open channel flow over a geometrically rough wall has been performed at a bulk Reynolds number of approximately 2900. The wall consisted of a layer of spheres in a square arrangement. Two cases have been considered.
