Abstract
The microstructure and rheology of suspensions can be characterized by using
low-order statistical moments of the orientation distribution function. This is
illustrated by calculating the orientation dyad and the fiber induced stress for
Couette flow between two eccentrically situated cylinders. Under the conditions
studied, the eigenvalues of the orientation dyad remain nonnegative throughout
the flow domain. The results are compared with other theories for the
microstructure that show unrealizable behavior under the same conditions.
Keywords: fiber suspensions, fiber orientation, non-Newtonian, closure model,
finite elements.
1 Introduction
The properties of short fiber composite are strongly influenced by the orientation
of the fibers in the fina
