Abstract
Coulomb explosions of small electrospray droplets of a high conductivity solution of a nonvolatile electrolyte in a volatile solvent are assumed to be nearly instantaneous events in which the exploding droplet loses certain fractions of its volume and charge by shedding a number of offspring droplets small compared with the parent droplet. Using this assumption, and leaving out the inertia of the droplets, an Eulerian model is proposed for the space evolution of a spray of electrified droplets which may undergo successive Coulomb explosions and may also reach an ion evaporation regime in which ions are emitted from their surface by field evaporation, until the solvent is virtually depleted.
期刊介绍:
Founded in 1970, the Journal of Aerosol Science considers itself the prime vehicle for the publication of original work as well as reviews related to fundamental and applied aerosol research, as well as aerosol instrumentation. Its content is directed at scientists working in engineering disciplines, as well as physics, chemistry, and environmental sciences.
The editors welcome submissions of papers describing recent experimental, numerical, and theoretical research related to the following topics:
1. Fundamental Aerosol Science.
2. Applied Aerosol Science.
3. Instrumentation & Measurement Methods.
