TLDR
In this article, the shape of the tip-ended axisymmetric, electrified meniscus with a conical tip was solved for the first time assuming negligible space charge, and the solution of this first-order, electrostatic problem yields not only the backbone result on a further perturbation scheme to solve the liquid and charge emission process, but also the old problem of that value of the potential difference at which the liquid is to be connected in order to achieve a tipended shape.About:

Nonlinear dynamics and breakup of free-surface flows
TL;DR: In this article, the authors review the theoretical development of this field alongside recent experimental work, and outline unsolved problems, as well as a host of technological applications, ranging from printing to mixing and fiber spinning.

Physics of liquid jets
Jens Eggers,Emmanuel Villermaux +1 more
TL;DR: A review of the fundamental and technological aspects of these subjects can be found in this article, where the focus is mainly on surface tension effects, which result from the cohesive properties of liquids Paradoxically, cohesive forces promote the breakup of jets, widely encountered in nature, technology and basic science.

Electrospinning and electrically forced jets. I. Stability theory
TL;DR: In this paper, an asymptotic approximation of the equations of electrohydrodynamics is developed so that quantitative comparisons with experiments can be carried out and the physical mechanisms for the instability are discussed in the various possible limits.
Journal ArticleDOI
Current and droplet size in the electrospraying of liquids. Scaling laws
TL;DR: In this article, the scaling laws of the spray current and droplet size were obtained from a theoretical model of the charge transport, and the separation between two different behaviours strongly related to the viscosity and electrical conductivity of the liquid was found.
Journal ArticleDOI
Electrospinning and electrically forced jets. II. Applications
TL;DR: In this paper, the shape and charge density of a steady jet as it thins from a millimeter-scale nozzle is calculated and combined with the stability analysis to predict scaling laws for the jet behavior and to produce operating diagrams for when electrospinning occurs.

Disintegration of Water Drops in an Electric Field
TL;DR: In this article, it was shown that a conical interface between two fluids can exist in equilibrium in an electric field, but only when the cone has a semi-vertical angle 49.3$^\circ$.

XX. On the equilibrium of liquid conducting masses charged with electricity
TL;DR: In this article, the equilibrium of liquid conducting masses charged with electricity was studied and the authors proposed a method to solve the problem of finding the equilibrium point of a liquid conducting mass with respect to electricity.

Boundary Elements: An Introductory Course
TL;DR: Boundary concepts are introduced and immediately applied in simple - but useful - computer codes that facilitate the comprehension of boundary elements.
Journal ArticleDOI
Electrically driven jets
TL;DR: Van Dyke as mentioned in this paper measured the potentials at which viscous jets or drops first appear in a parallel electric field and compared with calculations of A. B. Basset and found that their stability is due to mechanical rather than electrical causes, like a stretched string, which is straight when pulled but bent when pushed.
