Hydrodynamics substantially affects induced structure formation in magnetic fluids
Henning Reinken, Markus Heiber, Takeaki Araki +1
Magnetorheological fluids consist of micrometer-sized magnetic particles in a carrier liquid. Sufficiently strong external magnetic fields lead to the formation of string-like part…
Elastic displacements and viscous hydrodynamic flows in wedge-shaped geometries with a straight edge: Green's functions for parallel forces
Abdallah Daddi-Moussa-Ider, Lukas Fischer, Marc Pradas +1
For homogeneous and isotropic linearly elastic solids and for incompressible fluids under low-Reynolds-number conditions the fundamental solutions of the associated continuum equat…
Doubling the magnetorheological effect of magnetic elastomers
Lukas Fischer, Andreas M. Menzel
One of the most important properties of soft functionalized magnetic composite materials in view of their technological potential is given by the magnetorheological effect. It desc…
Rheologically tuned modes of collective transport in active viscoelastic films
Henning Reinken, Andreas M. Menzel
While many living biological media combine both viscous and elastic properties, most theoretical studies employ either purely fluid- or solid-like descriptions. We here use a unifi…
Unified description of viscous, viscoelastic, or elastic thin active films on substrates
Henning Reinken, Andreas M. Menzel
It is frequent for active or living entities to find themselves embedded in a surrounding medium. Resulting composite systems are usually classified as either active fluids or acti…
Self-sustained patchy turbulence in shear-thinning active fluids
Henning Reinken, Andreas M. Menzel
Bacterial suspensions and other active fluids are known to develop highly dynamical vortex states, denoted as active or mesoscale turbulence. We reveal the pronounced effect of non…
