Non-reciprocal Binary-fluid Turbulence
Biswajit Maji, Nadia Bihari Padhan, Axel Voigt +1
Although effective non-reciprocal interactions have been investigated in a variety of fields, their consequences have not been explored in hydrodynamical turbulence. We initiate su…
Self-avoiding fluid deformable surfaces
Maik Porrmann, Sören Bartels, Axel Voigt
We propose a numerical method for fluid deformable surfaces governed by surface Stokes flow and Helfrich bending energy under active growth, aiming to model shape evolution of the…
Self-organized flows break morphological symmetry in active/passive systems
Rainer Backofen, Axel Voigt
We consider a phase-separating mixture of active and passive fluids and explore morphological asymmetries of the emerging dominantly bicontinous dynamic emulsion. Two-dimensional n…
Vorticity-induced surfing and trapping in porous media
Pallabi Das, Mirko Residori, Axel Voigt +2
Microorganisms often encounter strong confinement and complex hydrodynamic flows while navigating their habitats. Combining finite-element methods and stochastic simulations, we st…
A numerical approach for the dynamics of active viscoelastic surfaces
Francine Kolley-Köchel, Jan Magnus Sischka, Axel Voigt +2
The dynamics of active viscoelastic surfaces plays an important role in biological systems. One prominent example is the actin cortex, a thin bio-polymer sheet underneath the outer…
Hyperuniformity in ternary fluid mixtures: the role of wetting and hydrodynamics
Nadia Bihari Padhan, Axel Voigt
Phase separation in multicomponent fluids is central to understanding the organization of complex materials and biological structures. The Cahn-Hilliard-Navier-Stokes (CHNS) equati…
