To solve problems in polymer fluid dynamics, one needs the equations of continuity, motion,
and energy. The last two equations contain the stress tensor and the heat-flux vector for the …

The Oldroyd 8-constant model is a continuum framework containing, as special cases, many
important constitutive equations for elastic liquids. When polymeric liquids undergo large …

Rheometry is an experimental technique that measures the relationship between stresses,
strains, and their derivatives of fluids and deformable materials. Capillary and Couette …

Hydrogels with or without chemical cross-linking have been studied and used for biomedical
applications, such as tissue repair, surgical sealants, and three dimensional biofabrication …

In this study, Stokes' second problem for Cu-Al 2 O 3/water hybrid nanofluid is considered
along with the effects of buoyancy force and a heat source. Using Laplace transforms …

We examine the simplest relevant molecular model for large-amplitude shear (LAOS) flow of
a polymeric liquid: the suspension of rigid dumbbells in a Newtonian solvent. We find explicit …

In this paper, we provide a new exact framework for analyzing the most commonly measured
behaviors in large-amplitude oscillatory shear flow (LAOS), a popular flow for studying the …

The Oldroyd 8-constant framework for continuum constitutive theory contains a rich diversity
of popular special cases for polymeric liquids. In this paper, we use part of our exact solution …

When polymeric liquids undergo large‐amplitude shearing oscillations, the shear stress
responds as a Fourier series, the higher harmonics of which are caused by fluid nonlinearity …

This paper investigates the influence of molecular properties (molecular weight,
polydispersity (PDI) and molecular weight distribution (MWD)) on the mechanical fatigue of …
