A comprehensive numerical procedure for solving the Taylor-Melcher leaky dielectric model with charge evaporation

Electrosprays in the pure-ion mode are of particular interest to space propulsion because of its ability to produce high specific impulse and efficient electrical-to-kinetic energy transformation, together with its simplicity and compactness. Unlike electrospray emitters operating in the droplet mode, pure-ion emission is known to be very dependent on the meniscus configuration, and consequently permissible under specific circumstances, mostly related to its stability. This has conferred pure-ion sources with an increased difficulty in controlling and predicting fundamental beam characteristics such as current emitted, while also making it hard to establish the conditions that need to be met by the device structure to support adequate ion emission. The use of Ionic Liquids has moderately alleviated some of these limitations, but still, the physics that lie behind electrosprays in the pure-ion regime remain considerably elusive.
