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. As a result, a general, unified de- scription of the complete parametrical space for the em...
