Tunable Drop Splashing on Magnetoactive Elastomers
نویسندگان
چکیده
The significant effect of an external dc magnetic field on the splashing behavior ethanol drops impacting unstructured (flat) surface soft magnetoactive elastomers (MAEs) is reported. Weber number corresponding to transition between deposition and regime reduced by ?20% in a moderate ?300 mT. Alongside this effect, two-fold increase initial deceleration ejection sheet observed for softest sample. main underlying mechanism phenomena believed be magnetic-field-induced stiffening MAEs. Further possible mechanisms are magnetically induced changes roughness plasticity (magnetic shape memory effect). potential application areas regulable wetting magneto-responsive surfaces controlling drop splashing.

Magnetoactive elastomers with periodic and random microstructures
We investigate the behavior of magnetoactive elastomers (MAEs) with periodic and random distributions of circular and elliptical fibers. For the MAEs with periodic microstructures, we develop finite element models and determine the local fields as well as the effective properties of MAEs with rectangular and quasi-hexagonal unit cells. For the MAEs with random microstructures, we derive a close...
متن کاملDrop splashing on a dry smooth surface.
The corona splash due to the impact of a liquid drop on a smooth dry substrate is investigated with high-speed photography. A striking phenomenon is observed: splashing can be completely suppressed by decreasing the pressure of the surrounding gas. The threshold pressure where a splash first occurs is measured as a function of the impact velocity and found to scale with the molecular weight of ...
متن کاملDynamics of initial drop splashing on a dry smooth surface
We simulate the onset and evolution of the earliest splashing of an infinite cylindrical liquid drop on a smooth dry solid surface. A tiny splash is observed to be emitted out of the rim of the lamella in the early stage of the impact. We find that the onset time of the splash is primarily dependent on the characteristic timescale, which is defined by the impact velocity as well as the drop rad...
متن کاملOrigin and dynamics of vortex rings in drop splashing
A vortex is a flow phenomenon that is very commonly observed in nature. More than a century, a vortex ring that forms during drop splashing has caught the attention of many scientists due to its importance in understanding fluid mixing and mass transport processes. However, the origin of the vortices and their dynamics remain unclear, mostly due to the lack of appropriate visualization methods....
متن کاملAir entrapment and splashing treshold in drop impacts .
We investigate here how the surrounding gas influence the dynamics of drop impacts on a thin liquid film. We describe in details the entrapment of the gas bubble using numerical simulations with high enough mesh resolution. The bubble entrapment comes from viscous effect in the thin gas layer that need to be evacuated down the drop, creating a high pressure field that deforms the drop interface...
