    Abstract

    Non-spherical particles dispersed in a Newtonian fluid have a tendency to align in shear flows because of viscous drag. This phenomenon is opposed by rotary diffusion induced by particle-particle interactions. At high concentrations and in the absence of hydrodynamic couples, self-alignment can also occur because excluded volume interactions prevent the return to isotropy of anisotropic states by rotary Brownian motion. The consequences of the foregoing balance between hydrodynamic and diffusive alignment processes on the microstructure directly impact the rheology and, thereby, the processing of suspensions. The objective of this research is to predict the microstructure and rheological properties of axisymmetric "ellipsoidal" particle suspensions in homogeneous flows.
