Abstract Experimental technique is proposed to excite oscillations of a hanging liquid droplet by applying interfacial dielectric force directly upon the droplet surface. The force proved to be applicable for all kinds of liquids and solutions including non-conductive, isolating liquids. The oscillations are detected optically, with the help of a laser beam. The measured resonant frequency modes and resonance half-widths may be used to retrieve information about the surface properties of the…

Droplet oscillations driven by an electric field
Abstract A new technique for examination of interfacial electric phenomena on droplet surface in real time is proposed. The technique is based on measuring the resonant frequency of spherical and
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
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
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.
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
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


The damping oscillation of a hanging drop on a nozzle in the air was studied theoretically and experimentally. In the experiments, an elongated drop on a brass nozzle by electrostatic force was made
The oscillating drop technique revisited
The oscillating drop technique—in combination with some kind of levitation—is widely used today for the measurement of the surface tension and viscosity of liquids. It is based on Rayleigh's theory
Internal flow of an electrostatically levitated droplet undergoing resonant shape oscillation
Experimental evidence of internal dc flow circulation within an electrostatically levitated, 3.4 mm diameter charged water drop oscillating in shape at a different amplitude is presented. The
Electrically stressed water drops in oil
The deformation of water droplets in an electric field has been studied in hydrocarbon liquids. A water drop will elongate in an electric field due to the electrostatic pressure, and becomes unstable
In experiments to measure the surface energy of a magnetically levitated molten metal droplet by observation of its oscillation frequencies, Rayleigh's equation is usually used. This assumes that the
Instrument and methods for surface dilatational rheology measurements.
We describe an instrument combining the advantages of two methods, axisymmetric drop shape analysis for well-deformed drops and capillary pressure tensiometry for spherical drops, both used for
Experimental and theoretical investigation of large-amplitude oscillations of liquid droplets
Finite-amplitude, axially symmetric oscillations of small (0.2 mm) liquid droplets in a gaseous environment are studied, both experimentally and theoretically. When the amplitude of natural

In this paper an appropriate extension of the virial method developed by Chandrasekhar is used to systematically re-examine the equilibrium and stability of an incompressible dielectric fluid drop
Surface Tension of Alcohol Water + Water from 20 to 50 .degree.C
The surface tension of mixtures is a physical property of great importance for mass transfer processes such as distillation, extraction, or absorption. The surface tension of aqueous solutions of
