Assessment of Analytical Orientation Prediction Models for Suspensions Containing Fibers and Spheres

Analytical orientation models like the Folgar Tucker (FT) model are widely applied to predict of suspended non-spherical particles. The accuracy these depends on empirical parameters. In this work, we assess how well analytical can suspensions not only consisting fibers but also an additional second particle type in shape disks, which varied size and filling fraction. We mainly focus FT model, compare its more complex Reduced-Strain Closure (RSC), Moldflow Rotational Diffusion (MRD), Anisotropic Rotary (ARD). our address following questions. First, despite phase affecting rotation fibers? Second, is it possible formulate expression for sole parameter that based suspension composition? Third, there advantage choose prediction require adjustment parameters?
