Abstract

The manifestations of instability in liquid droplets containing charged macroions relative to the Rayleigh limit are considered. It was found that beyond the Rayleigh limit, droplets become unstable and form structures with distinct features. Using computer modeling, the development of charge instability is presented. The effect of the instability mechanism on the breakup of charged droplets during electrospray is examined. The stability of charged conductive droplets with ellipsoidal shapes is investigated, highlighting the characteristics of ellipsoidal deformations and the dependence of surface force density on various values of the Rayleigh parameter.
