Efficient single-precision simulations of nematohydrodynamics
Guilherme N. C. Amaral, Mahmoud Sedahmed, Margarida M. Telo da Gama +1
Simulations of nematohydrodynamics on graphics processing units (GPUs) are typically performed using double precision, which ensures accuracy but significantly increases computatio…
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…
Study of fluid displacement in 3D porous media with an improved multi-component pseudopotential lattice Boltzmann method
M. Sedahmed, R. C. V. Coelho, N. A. M. Araújo +2
We generalize to three dimensions (3D) a recently developed improved multi-component pseudopotential lattice Boltzmann method and analyze its applicability to simulate flows throug…
An improved multicomponent pseudopotential lattice Boltzmann method for immiscible fluid displacement in porous media
M. Sedahmed, R. C. V. Coelho, H. A. Warda
Immiscible fluid displacement in porous media occurs in several natural and industrial processes. For example, during petroleum extraction from porous rock reservoirs, water is use…
