Bridging advection and diffusion in the encounter dynamics of sedimenting marine snow
Jan Turczynowicz, Radost Waszkiewicz, Jonasz Słomka +1
Sinking marine snow particles, composed primarily of organic matter, control the global export of photosynthetically fixed carbon from the ocean surface to depth. The fate of sedim…
Slower swimming promotes chemotactic encounters between bacteria and small phytoplankton
Riccardo Foffi, Douglas R. Brumley, François Peaudecerf +2
Chemotaxis enables marine bacteria to increase encounters with phytoplankton cells by reducing their search times, provided that bacteria detect noisy chemical gradients around phy…
Fluid flow generates bacterial conjugation hotspots by increasing the rate of shear-driven cell-cell encounters
Matti Zbinden, Jana S. Huisman, Natasha Blitvic +2
Conjugation accelerates bacterial evolution by enabling bacteria to acquire genes horizontally from their neighbors. Plasmid donors must physically encounter and connect with recip…
Vortex line entanglement in active Beltrami flows
Nicolas Romeo, Jonasz Slomka, Jorn Dunkel +1
Over the last decade, substantial progress has been made in understanding the topology of quasi-2D non-equilibrium fluid flows driven by ATP-powered microtubules and microorganisms…
Emergent universal statistics in nonequilibrium systems with dynamical scale selection
Vili Heinonen, Abel J. Abraham, Jonasz Słomka +3
Pattern-forming nonequilibrium systems are ubiquitous in nature, from driven quantum matter and biological life forms to atmospheric and interstellar gases. Identifying universal a…
An optimal complexity spectral method for Navier--Stokes simulations in the ball
Nicolas Boullé, Jonasz Słomka, Alex Townsend
We develop a spectral method for solving the incompressible generalized Navier--Stokes equations in the ball with no-flux and prescribed slip boundary conditions. The algorithm ach…
Encounter rates between bacteria and small sinking particles
Jonasz Słomka, Uria Alcolombri, Eleonora Secchi +2
Bacteria in aquatic environments often interact with particulate matter. A key example is bacterial degradation of marine snow responsible for carbon export from the upper ocean in…
Anomalous chained turbulence in actively driven flows on spheres
Oscar Mickelin, Jonasz Słomka, Keaton J. Burns +4
Recent experiments demonstrate the importance of substrate curvature for actively forced fluid dynamics. Yet, the covariant formulation and analysis of continuum models for non-equ…
The nature of triad interactions in active turbulence
Jonasz Słomka, Piotr Suwara, Jörn Dunkel
Generalized Navier-Stokes (GNS) equations describing three-dimensional (3D) active fluids with flow-dependent spectral forcing have been shown to possess numerical solutions that c…
Stokes' second problem and reduction of inertia in active fluids
Jonasz Słomka, Alex Townsend, Jörn Dunkel
We study a generalized Navier-Stokes model describing the thin-film flows in non-dilute suspensions of ATP-driven microtubules or swimming bacteria that are enclosed by a moving ri…
Spontaneous mirror-symmetry breaking induces inverse energy cascade in 3D active fluids
Jonasz Słomka, Jörn Dunkel
Classical turbulence theory assumes that energy transport in a 3D turbulent flow proceeds through a Richardson cascade whereby larger vortices successively decay into smaller ones.…
Geometry-dependent viscosity reduction in sheared active fluids
Jonasz Słomka, Jörn Dunkel
We investigate flow pattern formation and viscosity reduction mechanisms in active fluids by studying a generalized Navier-Stokes model that captures the experimentally observed bu…
Generalized Navier-Stokes equations for active suspensions
Jonasz Słomka, Jörn Dunkel
We discuss a minimal generalization of the incompressible Navier-Stokes equations to describe the solvent flow in an active suspension. To account phenomenologically for the presen…
