Rheological equations of state are of great importance for characterization of polymer melts
and for simulation of polymer processing. This concise review considers tube model based …

While there has been much success in modeling the linear and nonlinear rheology of
monodisperse entangled linear polymers, progress in the constitutive modeling of polymeric …

We present and analyze a series of benchmark tests regarding the application of the
immersed boundary (IB) method to viscoelastic flows through and around non-trivial …

The feature of the flow front for polystyrene melts in injection molding is investigated in detail
in this article. To explore the generation and evolution processes of “V”-shape pattern in the …

This work analyses the high-strain extensional behavior of long-chain branched
polyethylenes, employing two novel extensional rheometer devices, the filament stretching …

Stress-optical measurements at a flow stagnation point in confined geometries such as the
cross-slot provide an elegant way to perform extensional testing for polymer melts. This …

This paper describes the structures created by assembling functionalised entangled
polymers and the effect these have on the rheology of the material. A polybutadiene (PBd) …

Flow-induced disentanglement (FID or CCR-D) and chain tumbling are two molecular
mechanisms typically observed in non-equilibrium molecular dynamics simulations of …

In this work, we extend the classical analysis of concentration fluctuations in polymer
solutions under shear flow to consider the same phenomenology under mixed (shear+ …

This paper is concerned with simulating the viscoelastic flow of polystyrene melts in different
contraction geometries based on single mode Rolie-Poly constitutive model. The 4: 1 abrupt …
