M.Dielectric liquidsDrop breakupPolarizationArticle number 092114We study experimentally and numerically the thinning of Newtonian leaky-dielectric filaments subjected to an axial electric field. We consider moderately viscous liquids with high electrical permittivity. We analyze the influence of the electric field on the formation of satellite droplets from the breakup of the filaments in the experiments. The electric force delays the free surface pinching. Two electrified filaments with the same minimum radius are thin at the same speed regardless of when the voltage is applied. The numerical simulations show that the polarization stress is responsible for the pinching delay observed in the experiments. Asymptotically close to the pinching point, the filament pinching is dominated by the diverging hydrodynamic forces. The polarization stress becomes subdominant even if this stress also diverges at this finite-time singularity. © 2021 Author(s).Ministerio de Economía, Industria y Competitividad (España) PID2019–108278RBJunta de Extremadura GR18175American Institute of Physics Inc.Ingeniería Aeroespacial y Mecánica de Fluidos2021info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://hdl.handle.net/11441/130712https://doi.org/10.1063/5.0064473reponame:idUS.
