TL;DR: In this article, the effect of shear on the phase ordering of a two-dimensional binary fluid is studied using lattice Boltzmann simulations, and the authors show how the interplay between the ordering effects of the spinodal decomposition and the disordering tendencies of the shear can lead to a state of dynamic equilibrium where domains are continually broken up and reformed.

TL;DR: In this article, the authors study a continuum model of an extensile active nematic and show that mesoscale turbulence develops in two stages: (i) ordered regions undergo an intrinsic hydrodynamic instability generating walls, lines of stong bend deformations, and the walls relax by forming oppositely charged pairs of defects.

TL;DR: The capillary filling of microchannels is affected by posts or ridges on the sides of the channels, which slows, or sometimes prevents, filling, whereas ridges parallel to the flow provide extra surface that may enhance filling.

TL;DR: In this article, the kinetics of domain growth of a two-dimensional fluid quenched from a disordered to a lamellar phase are investigated. But the authors focus on the early stages of the growth process, when hydrodynamic modes become important, or the fluid is subjected to shear.

TL;DR: Dynamical simulations of a two-dimensional active nematic fluid in coexistence with an isotropic fluid show an effective anchoring develops at the nematic-isotropic interface, and quenching the active lyotropic fluid results in a steady state.
