(102g) Orientation, Microstructure and Rheology in Sheared Suspensions of Anisotropic Dicolloidal Particles

The orientation, microstructure and rheology in non-Brownian shear flow was studied for suspensions of dicolloidal particles using a novel PME Stokesian Dynamics algorithm for anisotropic particles. Four different particle shapes were studied with dicolloids modelled as the union of two intersecting spheres. Dynamic simulations were conducted for periodic systems of 1000 particles for volume fractions phi=0.05 to 0.55. The suspension microstructure was disordered for all particle shapes at 0
