Active nematic fluids confined in narrow channels are known to generate spontaneous flows when the activity is sufficiently intense. Recently, it was demonstrated [R. Green, J. Toner, and V. Vitelli, Phys. Rev. Fluids 2, 104201 (2017)] that if the mo

For a sperm-cell-like flagellated swimmer in an unbounded domain, several numerical models of different fidelity are considered based on the Stokes flow approximation. The models include a regularized Stokeslet method and a three-dimensional finite-e

Guided by extensive numerical simulations, we propose a microfluidic device that can sort elastic capsules by their deformability. The device consists of a duct embedded with a semi-cylindrical obstacle, and a diffuser which further enhances the sort

The scaling laws for the reconnection of isolated pairs of quantised vortices are characterised by numerically integrating the three-dimensional Gross–Pitaevskii equations, the simplest mean-field equations for a quantum fluid. The primary result i

We study the motion of an elastic capsule through a microchannel characterized by a localized constriction. We consider a capsule with a stress-free spherical shape and impose its steady-state configuration in an infinitely long straight channel as t

Perhaps because turbulence is central to a variety of applications for atmospheric and oceanic flows, as well as engineering, and yet remains largely unsolved, high-performance computing plays a central role, on par with observa tions and experiments

We perform two high-resolution direct numerical simulations of stratified turbulence for Reynolds number equal to Re ≈ 25 000 and Froude number, respectively, of Fr ≈ 0.1 and Fr ≈ 0.03. The flows are forced at large scale and discretized on an

There is a clear distinction between simple laminar and complex turbulent fluids; however, in some cases, as forthe nocturnal planetary boundary layer, a stable and well-ordered flow can develop intense and sporadic bursts of turbulent activity that

Quantum vortex dynamics in Bose-Einstein condensates or superfluid helium can be informatively described by the Gross-Pitaevskii (GP) equation. Various approximate analytical formulas for a single stationary vortex are recalled and their shortcomings

A numerical study of decaying stably stratified flows is performed. Relatively high stratification (Froude number ≈10 −2 - 10 −1 ) and moderate Reynolds (Re) numbers (Re≈ 3 -6 ×10 3) are considered and a particular emphasis is placed on the
