Influence of polymer concentration and nozzle material on centrifugal fiber spinning

J Merchiers, W Meurs, W Deferme, R Peeters… - Polymers, 2020 - mdpi.com
Centrifugal fiber spinning has recently emerged as a highly promising alternative technique
for the production of nonwoven, ultrafine fiber mats. Due to its high production rate, it could …

Reduced viscosity for flagella moving in a solution of long polymer chains

Y Zhang, G Li, AM Ardekani - Physical Review Fluids, 2018 - APS
The bacterial flagellum thickness is smaller than the radius of gyration of long polymer chain
molecules. The flow velocity gradient over the length of polymer chains can be nonuniform …

[HTML][HTML] Multi-resolution polymer Brownian dynamics with hydrodynamic interactions

E Rolls, R Erban - The Journal of Chemical Physics, 2018 - pubs.aip.org
A polymer model given in terms of beads, interacting through Hookean springs and
hydrodynamic forces, is studied. A Brownian dynamics description of this bead-spring …

Stress-gradient-induced migration effects on the elastic instabilities of wormlike micellar solutions in a cross-slot flow

FS Forte Neto, AGB da Cruz - Physics of Fluids, 2021 - pubs.aip.org
Using the two-species VCM model, we report the effects of stress-gradient-induced
migration on the elastic instabilities of a wormlike micellar solution flowing through a cross …

Hydrodynamic bifurcation in electro-osmotically driven periodic flows

A Morozov, D Marenduzzo, RG Larson - Physical Review Fluids, 2018 - APS
In this paper, we report an inertial instability that occurs in electro-osmotically driven channel
flows. We assume that the charge motion under the influence of an externally applied …

Studying partially ordered systems using stochastic differential equations

E Rolls - 2018 - ora.ox.ac.uk
This thesis looks at two different problems in the field of partially ordered systems-modelling
biopolymers on multiple scales as well as modelling two-dimensional nematic liquid crystal …
