Abstract: For a dispersion containing small charged macro-particles, the steady-state shear-viscosity and other viscosity coefficients are calculated. The deformation of the electrical double layer around the macro-particles is taken into account upto first order in the Péclet number. The viscosity coefficients are expressed as integrals over the (non-equilibrium) structure factor, and are thus valid up to “higher orders” in volume fraction. The deformation of the static structure factor due to the shear-flow is also discussed. It turns out that the structure factor is non-analytic in the shear-rate for small shear-rates.
