The electrical breakdown of solid dielectrics in non-uniform fields

Journal of Physics D: Applied Physics, 1972
The electrical breakdown of KBr, polyethylene and polymethylmethacryalate in non-uniform fields is considered. The observed breakdown voltage polarity effect, previously considered anomalous to current theories in which breakdown is governed by attainment of critical conditions at the cathode, is shown to be compatible to such theories if the effect of

A model for bubble motion in non-uniform electric fields

2008 IEEE International Conference on Dielectric Liquids, 2008
Electrohydrodynamic effects on bubble motion in dielectric fluids has found positive application for enhanced boiling heat transfer, for example in refrigerators. However the motion of bubbles in columns of dielectric fluid is also of interest where the presence of bubbles may adversely affect the breakdown performance of the liquid dielectric when ...

Enhanced heat flux in non-uniform electric fields

Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1973
Abstract Heat transfer by convection from a thin wire to a liquid was very appreciably increased by the application of a non-uniform electric field of several hundred kilovolts per centimetre which was confocal with the temperature field.

Examination of Kerr effects of non-uniform electric fields

1982 IEEE International Conference on Electrical Insulation, 1982
The Kerr effect has been used for many years to study space charge variation and make electrical measurements, Measurements are normally made with two parallel plates surrounded with nitrobenzen, or other suitable Kerr liquid. The plate to separatien size ratio is normally kept large to assure uniform fields for measurement.

Effect of non-uniform electric fields on drift instabilities

Plasma Physics, 1970
A general equation describing drift instabilities in a low beta plasma, in the presence of non-uniform electric fields perpendicular to the magnetic field, is derived using a guiding centre fluid picture for the ions and the drift kinetic equation with Krook-like collision term for the electrons.

Electron diffusion in a non-uniform electric field and a uniform magnetic field

Acta Physica Sinica (Overseas Edition), 1996
A Monte Carlo simulation technique has been used to model the electron transport behavior, especially the electron diffusion motion, in the cathode fall region of a glow discharge under the influence of a non-uniform electric field and a transverse magnetic field perpendicular to the cathode sheath electric field.

Particle Separation by Employing Non-Uniform Electric Fields, Traveling-Wave Electric Fields and Inclined Gravity

Intelligent Automation & Soft Computing, 2012
Abstract In this study, we present the methods of the particle separation by employing electrokinetic phenomena (dielectrophoresis (DEP) and traveling-wave electroosmosis (TWEO)) and the inclined gravity. The methods can separate particles of same sign DEP. However, it is very difficult to separate particles on a plane electrode.

Phase separation dynamics of simple liquids in non-uniform electric fields

The Journal of Chemical Physics, 2014
Spatially non-uniform electric fields can phase separate initially homogeneous mixtures of liquids. Here, we investigate the dynamics of phase separation using a modified Cahn-Hilliard equation and find three kinetically distinct regimes in the phase diagram: (1) discontinuous and (2) continuous interface formation kinetics and (3) a metastable state ...

Modelling electron kinetics in non-uniform electric fields

Plasma Sources Science and Technology, 1993
Summarizes various numerical descriptions of charged particle kinetics which are self-consistent with the electric field, and in situations where both space and time variations of the field must be considered. A brief review of two self-consistent kinetic methods is presented, along with a discussion of their respective strengths and weaknesses.

The Influence of Non-Uniform Electric Fields on Combusion Processes

1996
This report investigates the application of electric fields to flames and fires. An extensive literature review covers the empirical data available on the electric field effects on combustion characteristics. Authors attribute the mechanism to electrostatic forces on ions and an electrically induced air movement called corona wind Experimentation was ...
