Oscillatory Motion of Microdroplets of a Droplet Cluster in a Linearly Nonuniform Electric Field

详细

The forces acting on freely levitating water microdroplets in the structure found 15 years ago and called the droplet cluster (A. A. Fedorets, 2004) are considered. It is shown that lowfrequency vertical damping microdroplet oscillations can take place in such a cluster near the equilibrium position, which also exist in the case of instantaneous turn-on of an external electric field. These oscillations are considered from the viewpoint of the Fourier analysis.
