This article provides a review of recent progress in understanding and predicting polymer
drag reduction (DR) in turbulent wall-bounded shear flows. The reduction in turbulent friction …

Owing to nonlinear viscoelasticity, materials often show characteristic features that resemble
those of thixotropy. This issue has been debated in the literature over the past several …

We survey the field of micro-macro numerical techniques for predicting complex flows of
viscoelastic fluids. The micro-macro approach couples the mesoscopic scale of kinetic …

In this paper, we introduce a new method for solving efficiently the Fokker–Planck equation
arising in the simulation of dilute polymeric solutions. For a two-dimensional FENE (Finitely …

The effects of elasticity on filament thinning and breakup are investigated in microchannel
cross flow. When a viscous solution is stretched by an external immiscible fluid, a low 100 …

High-elasticity simulations of flows through a two-dimensional (2D) 4: 1 abrupt contraction
and a 4: 1 three-dimensional square–square abrupt contraction were performed with a finite …

Many important biological functions depend on microorganisms' ability to move in
viscoelastic fluids such as mucus and wet soil. The effects of fluid elasticity on motility remain …

A numerical method based on the Fokker–Planck equation is applied to the simulation of a
dilute solution of polymer modelled by two-dimensional FENE dumbbells. The proposed …

We investigate the effects of fluid elasticity on the dynamics of filament thinning and drop
breakup processes in a cross-slot microchannel. Elasticity effects are examined using dilute …

We address the closure problem for the most elementary non-linear kinetic model of a dilute
polymeric solution, known as the Warner finitely extensible non-linear elastic (FENE) …
