Particle motion and drift in non-uniform electric fields
Physics of Plasmas, 2023This paper analyzes the two-dimensional motion of a charged particle in constant mutually perpendicular electric and magnetic fields. The magnetic field is assumed to be uniform, and the electric field components are assumed to be linear functions of the Cartesian coordinates.

Electrocoalescence in non-uniform electric fields: An experimental study
Chemical Engineering and Processing: Process Intensification, 2015Abstract The method of electrostatic force-assisted phase separation is widely used in the chemical industry. The fast and clean separation capabilities make electrocoalescence a favorite among the other competing phase separation techniques. In the present study, we experimentally investigated the relative merits of symmetric and asymmetric non ...

The electrical breakdown of solid dielectrics in non-uniform fields
Journal of Physics D: Applied Physics, 1972The 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

Numerical analysis of quantum-mechanical non-uniform E×B drift: Non-uniform electric field [PDF]
International Journal of Applied Electromagnetics and Mechanics, 2016 We have numerically solved the two-dimensional time-dependent Schrödinger equation for a charged particle in the presence of a non-uniform electric field E = E ≤(1- y / L_E ) e_y as well as a non-uniform magnetic field B = B ≤(1- y / L_B ) e_z. It is shown that such a non-uniformity of the electric field does not affect the time rate of the variance ...

A model for bubble motion in non-uniform electric fields
2008 IEEE International Conference on Dielectric Liquids, 2008Electrohydrodynamic 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, 1973Abstract 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, 1982The 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, 1970A 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), 1996A 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.

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.
