Firstly, we have studied the shrinkage and breakup of neutral tori through Rayleigh-Plateau instabilities. When charged, electrical stresses can overcome surface tension stresses leading to droplet expansion. At even higher voltage, tori can develop Saffman-Taylor instabilities, which result in viscous fingering. Remarkably, at high enough potential, these viscous fingering branch out, giving rise to a magnificent dendritic-growth behaviour5 p.application/pdfengcc-by-nc-nd (c) Herranz, 2021http://creativecommons.org/licenses/by-nc-nd/3.0/es/LíquidsInestabilitatTreballs de fi de grauLiquidsInstabilitiesBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
