A diffuse-interface theory of active nematic interfaces: transport mechanisms and modal structure
Rodrigo C. V. Coelho, Mykola Tasinkevych, Margarida M. Telo da Gama
We develop a long-wavelength theory for the linear stability of a flat interface between an active nematic and an isotropic fluid. Starting from a diffuse-interface Cahn--Hilliard-…
Spontaneous rotation and propulsion of suspended capsules in active nematics
Júlio P. A. Santos, Margarida M. Telo da Gama, Rodrigo C. V. Coelho
We investigate the dynamics of elastic capsules suspended in two-dimensional active nematic fluids using lattice Boltzmann simulations. The capsules, modeled as flexible membranes…
Shape transitions of sedimenting confined droplets and capsules: from oblate to bullet-like geometries
Danilo P. F. Silva, Rodrigo C. V. Coelho, Ariel Dvir +4
The transport and deformation of confined droplets and flexible capsules are central to diverse phenomena and applications, from biological flows in microcapillaries to industrial…
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…
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…
Active nematic pumps
Ignasi Vélez-Ceron, Rodrigo C. V. Coelho, Pau Guillamat +4
Microfluidics involves the manipulation of flows at the microscale, typically requiring external power sources to generate pressure gradients. Alternatively, harnessing flows from…
