Abstract The influence of the supporting surface on the resonant frequency of pendant droplets has been examined experimentally. It has been shown that for spherical pendant droplets the correction term due to the boundary conditions at the supporting surface depends on the geometry and material of the supporting element, but also on the liquid of the droplet, which makes calibration impossible. In contrast, for hemispherical pendant droplets the influence of the boundary conditions can be kept…

Evaporation-rate dynamics of a hemispherical, pendant liquid droplet, influenced by resonant oscillations
Abstract An oscillating hemispherical pendant droplet has been used as an instrument to modify evaporation conditions of simple and complex liquids. The resonant droplet vibrations can influence the
Oscillation mode and resonant frequencies of spherical pendant droplets
An experimental study of the lowest resonant mode of spherical and hemispherical pendant droplets with low Bond numbers (less than 0.1) is proposed. The resonant frequency was determined by Resonant
Resonant droplet tensiometry driven by an electric field
A submillimeter sized pendant spherical droplet is placed in a nonuniform electric field. Combination of AC and DC electric field generates a frequency modulated dielectrophoretic force. Caused by
Gas-adsorption dynamics at the water–air interface, revealed by resonant droplet tensiometry
Abstract A resonant hemispherical pendant droplet tensiometry has been used to register in real time the change of surface tension of low Bond number water droplets due to evaporation of simple
Constrained droplet eigenfrequency approach in nanodroplets research
This work is dedicated to the study of weak capillary oscillations of supported spherical droplets with fixed (static, anchored) contact-line, and proposes the idea for the eigenfrequency approach in the nanodroplets research.
