Numerical method for inertial migration of particles in 3D channels

Abstract : The aim of this paper is to propose a method to model and numerically simulate the inertial migration of particles in three-dimensional channels. The initial problem, coupling Navier-Stokes equations to the equations modeling the displacement of a spherical particle immersed in the fluid, is replaced by a first order expansion with respect to a small Reynolds number. We reduce the computation of the velocity of a spherical particle situated at a given position in a channel to the numerical solutions of several Stokes elementary problems. The proposed method is employed to numerically approach the steady solutions for different domain configurations.
