Experimental Investigation of Flow Field Inside a Taylor Cone

EasyChair Preprint 2225

Abstract

Electrohydrodynamic atomization is a technique to produce small size (diameter in the range of $\mu$m--nm), mono-disperse particles of liquid by the application of a strong electric field. Under the action of electrical force, the meniscus of fluid at the nozzle exit is elongated and a Taylor cone jet is formed. The present work investigates the flow field induced inside the Taylor cone. The induced flow field has been studied experimentally by using flow visualization and particle image velocimetry techniques. The presence of toroidal vortex has been observed and it is found that the velocity inside the Taylor cone is of the order of mm/s.

Keyphrases: Electrohydrodynamic atomization, Particle Image Velocimetry, Taylor cone, Toroidal vortex, flow field
