Abstract: A high-resolution video recording of gravitational pinch-off of the freely falling drop additionally affected with an external electrostatic field is carried out. The evolution of the shape and dynamics of motion of the structural components both the droplet itself and the satellite, as well as the secondary satellite in the absence of an electric field, is traced. Estimates of the total energy components, dominate scales and dimensionless parameters of the flow under study are given.
Keywords: drop, gravity, electrostatic field, shape evolution, high-voltage source, high-speed video filming.
