    Abstract The rheological behavior of fluid-particle suspensions affects the flow dynamics of natural processes such as lavas, flow-type landslides and sediment transport. This study presents results of fully resolved simulations of monodisperse non-Brownian suspensions in a Couette flow using the smoothed particle hydrodynamics (SPH) method coupled with discrete element method (DEM), which allows for simulation of arbitrary-shaped particles. Several benchmark tests have been conducted to verify the reliability of the method. Two density ratios are considered in the study, i.e., 2.65 and 10, with the average particle area fraction varying from 14% to 47% and particle More >
