Lubrication-Induced Newtonianization Enables Passive Transport of Non-Newtonian materials
Arvind Arun Dev, Paszkal Papp, Thomas M. Hermans +1
Non Newtonian flows are typically governed by intrinsic bulk rheology, which imposes strong constraints on transport through confined geometries. Here, we show that stable boundary…
Ultra-soft liquid-ferrofluid interfaces
Arvind Arun Dev, Thomas Hermans, Bernard Doudin
Soft interfaces are ubiquitous in nature, governing quintessential hydrodynamics functions, like lubrication, stability and cargo transport. It is shown here how a magnetic force f…
Scaling and flow profiles in magnetically confined liquid-in-liquid channels
Arvind Arun Dev, Florencia Sacarelli, G Bagheri +6
Ferrofluids kept in place by permanent magnet quadrupoles can act as liquid walls to surround a second non-magnetic inside, resulting in a liquid fluidic channel with diameter size…
Suppressing Rayleigh-Plateau Instability with a Magnetic Force Field for Deformable Interfaces Engineering
Arvind Arun Dev, Thomas Hermans, Bernard Doudin
The Rayleigh-Plateau instability (RPI) is a classical hydrodynamics phenomenon that prevents a jet of liquid to flow indefinitely within air or another liquid. Here, we show how ad…
