Fig. 3. Electrostatic pressure distribution, Pel, in the ambient phase and along the droplets free surface for the different dielectric cases (a) d = 5 μm and (b) d = 50 μm (η = 0.8). The arrows follow the electric field vector (are normal to the droplets free surface) and correspond to the directionality of the electrostatic pressure distribution along the liquid-ambient interface at the three-phase contact line (TPL).
