An enhanced discrete element method for the numerical modelling of particulate media is presented. This method models a particle of general shape by combining several smaller particles of simpler shape, such as a circle, into clusters that act as a single larger particle. The clusters more accuratel

Motion of a particle suspending in a Newtonian fluid subject to an external force and flow becomes complex if the particle shape is not simple. For example, a propellar like particle rotates as it settles down, and a helical particle migrates normal to the ambient fluid velocity in shear flow. These
