Project Description

In multiphase flow, the models used to describe the resence of particles in a fluid usually ignore the force interaction among particles and a fluid flow governed by the Navier-Stokes' equations. In order to gain some insight into the physical phenomena in a "micro" flow environment, we study the interaction among fixed and moving solid spheres and the surrounding fluid. Due to the presence of attracting and repelling forces that depend on the geometrical configurations, one can expect an intensive and complex motion of the particles when they are allowed to move freely. Due to this effect simple rheological (isotropic) models are inadequate.
