Abstract

For the first time, synchronized video recording of the flow pattern and acoustic pressure by a hydrophone was performed during the merging of a falling drop of distilled water with a liquid at rest in an electrostatic field. The generator anode is connected to the tip of a capillary drop dispenser, the flat cathode is placed on the bottom of a pool filled with tap water. In the impact flow mode, when the kinetic energy of the falling drop significantly exceeds its potential surface energy, a reduction in the chronogram duration, a refinement of the flow pattern and an increase in the frequency of the resonant packet are observed when the electrostatic field is applied. The observed changes indicate a strong influence of the electrostatic field on the structure of droplet flows in the phase of formation and separation of gas cavities emitting resonant acoustic signals.
