Abstract

Shear-induced particle migration was investigated by using a continuum diffusive-flux model for the creep flow of nickel-powder-filled polymers, which is viscous with shear-thinning characteristics. The model, together with flow equations, was employed for solving the generalized-Newtonian flow patterns and non-uniform particle concentration distribution of mono-modal suspensions in a pressure-driven tube flow. Particle volume fraction and velocity fields for the non-homogeneous shear flow field were predicted with different particle concentrations. Effects of different viscosity models of the binder system on particle migration during non-homogeneous shear fluid flow were investigated.
