Solute dispersion in pre-turbulent confined active nematics
Tomás Alvim, Margarida M. Telo da Gama, Rodrigo C. V. Coelho
We investigate the dispersion of solutes in active nematic fluids confined in narrow channels based on simulations of nematohydrodynamics. The study focuses on two pre-turbulent re…
Liquid crystal torons in Poiseuille-like flows
Guilherme N. C. Amaral, Hanqing Zhao, Mahmoud Sedahmed +5
Three-dimensional (3D) simulations of the structure of liquid crystal (LC) torons, topologically protected distortions of the LC director field, under material flows are rare but e…
Wetting and pressure gradient performance in a lattice Boltzmann color gradient model
Mahmoud Sedahmed, Rodrigo C. V. Coelho
An accurate implementation of wetting and pressure drop is crucial to correctly reproducing fluid displacement processes in porous media. Although several strategies have been prop…
"Hall" transport of liquid crystal solitons in Couette flow
Rodrigo C. V. Coelho, Hanqing Zhao, Guilherme N. C. Amaral +3
Topology establishes a unifying framework for a diverse range of scientific areas including particle physics, cosmology, and condensed matter physics. One of the most fascinating m…
Active nematic-isotropic interfaces on flat surfaces: effects of anchoring, ordering field and activity
Rodrigo C. V. Coelho, José A. Moreira, Duarte M. C. Pedro +1
A surface in contact with the isotropic phase of a passive liquid crystal can induce nematic order over distances that range from microscopic to macroscopic when the nematic-isotro…
