The effect of polydispersity on the stresses of cylindrical particle flows

The Discrete Element Method (DEM) simulations are performed to investigate shear flows of polydispersed, cylindrical particles. Binary mixtures and Gaussian distribution mixtures are considered in the simulations to study the effect of polydispersity on the rheology and particle phase stresses. It is observed that no segregation occurs in the shear flows in the absence of gravity and interstitial fluid medium and the orientational alignment of a...
