N2 - Suspensions of rigid aggregates have been investigated by Stokesian dynamics. In our recent work (Seto R, Botet R, Briesen H. Phys Rev E 84:041405, 2011), the motions of freely suspended aggregates in shear flows were determined by considering the force and torque balance, and forces and moments acting on the contact points within aggregates were also evaluated. Here, by comparing the obtained results with a bond strength between particles, the sustainable sizes of the aggregates under shear flows have been estimated, which leads to a viscosity-shear rate relation. Our method allows us to see not only the power-law shear thinning for fractal aggregates but also some deviations due to the finite-size effects.
