Modeling and numerical simulations of Brownian rodlike particles with anisotropic translational diffusion

Abstract

The suspension of Brownian rods in flow has a major effect in many engineering applications. We numerically examine Brownian rod suspensions through a rectangular channel with and without the effect of circular obstacles, taking into consideration the isotropic translational diffusion tensor using the finite element method. We develop a kinetic macro-model that reduces the computational effort of the Brownian rod suspensions and it gives a good approximation with errors less than 5%.
