A constitutive equation for fiber suspensions in viscoelastic media

A viscosity overshoot of fibers filled in a polymer melt under shear flow is much tougher to predict via the existing constitutive equations suspension rheology viscous media, owing effect fiber orientation on viscoelastic behavior. The WMT-X (White–Metzner model eXtended by Tseng) fluid coupled with typical Dinh–Armstrong model, known as suspended proposed herein. primary procedure involves verifying lower completely aligned compared that randomly oriented suspension. In addition, depends off-diagonal tensor component flow-gradient plane. As validation, numerical predictions transient are good agreement related experimental data.
