On the general scaling theory for electrospraying
A systematic dimensional rationale is proposed here to analyse the electrohydro- dynamic equations governing liquid electrospraying phenomena in the well-known steady cone-jet mode with no ambient discharges.

| Sumario: | A systematic dimensional rationale is proposed here to analyse the electrohydro- dynamic equations governing liquid electrospraying phenomena in the well-known steady cone-jet mode with no ambient discharges. As a result, a general, unified de- scription of the complete parametrical space for the emitted current and droplet size is given. Four main distinct subspaces, their relevant boundaries and corresponding scal- ing laws are identified. Laws already proposed fit in their appropriate region, and previously unknown laws are found. A closed solution for the electric current I when inertia and polarization forces dominate is obtained, in agreement with published experimental results. |
