“…Due to the contactless control methods enabled accordingly, droplets made of ferrofluids are attracting significant interest as new archetypal systems for the improvement of some of the processes discussed above or simply for the definition and exploration of new paths of fundamental research (see, e.g. Hong et al, 2007;Korlie et al, 2008;and references therein). In particular, most of existing studies on ferrofluid droplets have concentrated primarily on their equilibrium shape and stability under the effect of magnetic fields with different properties (often on the basis of a mathematical "analogue", namely, a dielectric droplet in a uniform electric field, see, e.g., Bacri and Salin, 1982;Sherwood, 1988 andStone et al, 1999;Lavrova et al, 2004;Zhu et al, 2011).…”
