Low shear viscosity of a dense ionic micellar solution

We present a method for evaluating the low shear viscosity of a strongly interacting nonspherical micellar solution. The contribution from hydrodynamic interaction was calculated according to the Batchelor-Green equation with the effect of micellar shape and the hydration taken into account. The Brownian contribution was calculated by modifying the method of de Schepper, Smorenburg, and Cohen [Phys. Rev. Lett. 70, 2178 (1993)] with the structure factor extracted from a small angle neutron scattering experiment. The low shear viscosity agrees with the experimental results for hydrated micellar volume fraction phi(m) up to 0.4.
