- Summary
- Our experimental results clearly demonstrate that the shape of particles with aspect ratio close to unity dictates the relative suspension viscosity. Suspensions of irregularly shaped particles have higher relative viscosities than suspensions of spherical particles at same volume fractions, in agreement with the reported results at high shear conditions. The relative viscosity of a Newtonian suspension is in excellent agreement with that predicted by the Krieger/Dougherty rigid sphere model using the maximum packing fraction determined from sedimentation as the sole parameter. The relative viscosity of a pseudoplastic suspension is independent of the particle density. It correlates well with the particle Peclet number. The extent of particle diffusion at high shear rates decreases considerably as the particle size increases, and less energy is dissipated as a result. The interparticle electrostatic repulsion plays no significant role in the rheology of pseudoplastic nonaqueous and aqueous glycerol suspensions of noncolloidal particles.
