Since the late 1960s, several enhanced–oil–recovery (EOR) researchers have developed
various continuum and pore–scale viscoelastic models for quantifying the altered injectivity …

Viscoelastic polymer solutions exhibit a variety of flow instabilities and in particular, in mixed
shear and extensional flow, elastic turbulence. Coincident with the transition to turbulence is …

We investigate the use of Random Forest (RF) regression to estimate viscoelastic
constitutive model parameters using Large Amplitude Oscillatory Shear (LAOS). We deploy …

Polymer flooding is a common enhanced oil recovery (EOR) method used to increase
aqueous phase sweep efficiency by increasing viscosity. Estimating polymer viscosity for …

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 …

By using the generalized bracket approach of nonequilibrium thermodynamics, we recently
developed a new two-species model for wormlike micelles based on the flow-induced …

The deformation and rupture of viscoelastic droplet passing through cylinder obstacles in a
microchannel are investigated using OpenFOAM. The constitute relationship of droplet is …

The most pressing question to embark on polymer flood projects is whether a polymer can
be injected at economic rates while below reservoir parting pressure. There are several …

We consider shear flows that comprise of step changes in the shear rate. For these flows, we
derive analytic solutions of the Rolie-Poly constitutive equation. Our method involves piecing …

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 …
