Effect of particle deformability on shear thinning in a 3D channel
Danilo P. F. Silva, Rodrigo C. V. Coelho, Margarida M. Telo da Gama +1
Soft particles suspended in fluids flowing through microchannels are often encountered in biological flows such as cells in vessels. They can deform under flow or when subject to m…
Flow through time-evolving porous media: swelling and erosion
André F. V. Matias, Rodrigo C. V. Coelho, José S. Andrade +1
The flow through a porous medium strongly depends on the boundary conditions, very often assumed to be static. Here, we consider changes in the medium due to swelling and erosion a…
Director alignment at the nematic-isotropic interface: elastic anisotropy and active anchoring
Rodrigo C. V. Coelho, Nuno A. M. Araújo, Margarida M. Telo da Gama
Activity in nematics drives interfacial flows that lead to preferential alignment that is tangential or planar for extensile systems (pushers) and perpendicular or homeotropic for…
Propagation of active nematic-isotropic interfaces on substrates
Rodrigo C. V. Coelho, Nuno A. M. Araújo, Margarida M. Telo da Gama
Motivated by results for the propagation of active-passive interfaces of bacterial Serratia marcescens swarms [Nat. Comm., 9, 5373 (2018)] we use a hydrodynamic multiphase model to…
Lattice-Boltzmann simulation of free nematic-isotropic interfaces
Rodrigo C. V. Coelho, Nuno A. M. Araújo, Margarida M. Telo da Gama
We use a hybrid method of lattice Boltzmann and finite differences to simulate flat and curved interfaces between the nematic and isotropic phases of a liquid crystal described by…
Active nematic-isotropic interfaces in channels
Rodrigo C. V. Coelho, Nuno A. M. Araújo, Margarida M. Telo da Gama
We use numerical simulations to investigate the hydrodynamic behavior of the interface between nematic (N) and isotropic (I) phases of a confined active liquid crystal. At low acti…
