Equilibrium microstructure of complex fluids

Abstract

Predictions of the microstructure of complex fluids, such as liquid crystalline polymers or concentrated rigid rod suspensions, are often based on a moment equation for the orientation dyad that requires a closure model for the orientation tetrad. U is a dimensionless measure of the strength of the Maier-Saupe potential and accounts for the excluded volume self-alignment process on the rotary diffusive flux. In the absence of flow and for U > 5, the equilibrium states predicted by the above theory are anisotropic. Although an isotropic microstructure satisfies the steady steady-state moment equation for all values of U, a dynamic analysis of the orientation dyad shows that the isotropic state is stable for U 5.000.
