Easier sieving through narrower pores: fluctuations and barrier crossing in flow-driven polymer translocation
Rodrigo Ledesma-Aguilar, Takahiro Sakaue, Julia M. Yeomans
We show that the injection of polymer chains into nanochannels becomes easier as the channel becomes narrower. This counter intuitive result arises because of a decrease in the dif…
A circle swimmer at low Reynolds number
Rodrigo Ledesma-Aguilar, Hartmut Loewen, Julia M. Yeomans
Swimming in circles occurs in a variety of situations at low Reynolds number. Here we propose a simple model for a swimmer that undergoes circular motion, generalising the model of…
Three-dimensional aspects of fluid flows in channels. II. Effects of Meniscus and Thin Film regimes on Viscous Fingers
R. Ledesma-Aguilar, I. Pagonabarraga, A. Hernandez-Machado
We perform a three-dimensional study of steady state viscous fingers that develop in linear channels. By means of a three-dimensional Lattice-Boltzmann scheme that mimics the full…
Three-dimensional aspects of fluid flows in channels. I. Meniscus and Thin Film regimes
R. Ledesma-Aguilar, A. Hernandez-Machado, I. Pagonabarraga
We study the forced displacement of a fluid-fluid interface in a three-dimensional channel formed by two parallel solid plates. Using a Lattice-Boltzmann method, we study situation…
