Intrinsic viscosity of dispersions of core shell-particles

Zackrisson Oskolkova, Malin LU and Bergenholtz, Johan (2003) In Colloids and Surfaces A: Physicochemical and Engineering Aspects 225(1-3). p.119-127
Abstract
An analytic solution of the Brinkman and Stokes equations for a rigid sphere surrounded by a porous shell in pure

straining flow is presented. The solution permits for an analytic determination of the intrinsic viscosity in the dilutelimiting

expansion for the steady shear viscosity. The porous layer, characterized by a thickness and a constant

permeability, alters the intrinsic viscosity from the Einstein value. A hydrodynamic layer thickness based on the

intrinsic viscosity exhibits only a tenuous connection to the actual layer thickness within the present model. Together

with the analytical solution for the translational diffusion coefficient, derived previously by Masliyah and... (More)

used effective hard-sphere model (Less)
