Numerical Simulations of particle suspensions in confined

Abstract: Particle suspensions are ubiquitous in industry and natural phenomena. With the rapid development of micro-devices it becomes increasingly important to understand the behavior of owing particle suspensions in con ned geometries. Here, we perform numerical simulations of particles suspended in a channel in the inertial regime, when particle and uid inertia cannot be neglected. We study the variations of the suspension's eective viscosity and microstructure with con nement.
