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 Reynolds number varying from 0.15 to 4.5. Unlike most of 
the existing studies, we explore the effect of different particle aspect ratio and convexity. The influence of 
particle shape and inertia varying with the particle density and Reynolds number is studied, both of which 
significantly affect the contributions of particle-fluid and particle-particle interactions to the stress, leading 
to the change in the suspension rheology. Moreover, the anisotropy in microstructure is investigated 
through the pair distribution function g(r), and particle rotation is presented to show the particle 
kinematics.},
