Simulations for Pulsating Breakups of a Nano Taylor Cone

Abstract In this paper, a Taylor cone model in the nanoscale is configured using many-body dissipative particle dynamics method. The sharpening process of and breakup at different electric field intensities charge concentrations are systematically investigated. Under strong field, hemispherical droplet sharpened over time evolves into conic one. Then cusp emits thin jet. Finally, shrinks semi-sphere after jet breaking. These deformation processes occur several times until no charges emitted from cusp. It found that force responsible for emitting, while Coulombic causes breakup. With rising intensity also increase. However, decrease with concentration. indicates conductive liquid low electrical conductivities subjected to more prone undergo pulsating breakups.
