    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.
