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