Abstract

A nonlinear model has been developed to assess the time-dependent evo- lution of liquid surfaces exposed to electrostatic forces. The model pre- sumes the liquids are perfect conductors and are inviscid. A fully 4th-order nonlinear, coupled free surface treatment has been applied; nodes are redis- tributed at equal intervals using splines and a Runge-Kutta time integration scheme is employed. Results have been obtained for both droplets and liq- uid columns undergoing nonlinear oscillations and electrostatically-induced breakup. Introduction In many practical applications, there are significant advantages to the use of electrostatic atomization techniques. Today, this scheme is utilized in nu- merous fields as diverse as agricultural and automotive sprays, targeted drug delivery systems and ink-jet p
