Electric field simulation in a non-uniform field dielectric system

[1990] Proceedings. The Twenty-Second Southeastern Symposium on System Theory, 2002
The charge simulation method (CSM) is used to compute potential and electric field distribution in a 'hyperboloid-plane' electrode system. Electric field enhancement along the axis of the hyperboloid and within the dielectric is calculated at various interelectrode spacings and with various tip radii.

Modeling molecular response in uniform and non-uniform electric fields

The Journal of Chemical Physics, 2013
The response of a molecule to an electric field E, often a model of environment, can be expressed in terms of a sum of power series expansions. We investigate the accuracy and limits of applicability of this expression using one-, two-, and three-dimensional models of the hydrogen-bonded complex, ClH:NH3.

Particle motion and drift in non-uniform electric fields

Physics of Plasmas, 2023
This 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.

Energy landscapes for ellipsoids in non-uniform AC electric fields

Soft Matter, 2018
We report an analytical model for energy landscapes of ellipsoidal particles in non-uniform high-frequency AC electric fields to identify all possible 3D positions and orientations.

Electron Heating by Non-Uniform Electric Field

1974
Current-voltage characteristics of asymmetrically necked samples cut from uniform single crystal of germanium become asymmetric at high electric fields. Current instabilities due to impact ionization are observed. A dc electromotive force arises in such samples in a large microwave field.

Corrosion Behavior of Aluminum in Non‐Uniform Electric Fields

Journal of the Chinese Chemical Society, 2001
AbstractThe present paper discusses the effect of the geometrical structure of the electric fieldon the corrosion of aluminum cathodes by electrolysis of aqueous solutions of sodium chloride. A correlation between the mass of the aluminum dissolved from the cathode and the factors electric current density, distance between the electrodes, electrolysis ...

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 Townsend coefficient in non-uniform electric fields

Journal of Physics D: Applied Physics, 1991
A one-dimensional model of electron multiplication in a gas is considered by using a system of equations of moments. An approximate expression for the first Townsend ionization coefficient is derived. It is shown that for a linearly decreasing electric field, the multiplication cannot be characterized by a local transport coefficient, such as Townsend ...

Electrical breakdown of mineral oil under non-uniform fields

Journal of Physics D: Applied Physics, 1976
The dependence of the direct electrical breakdown voltage of degassed transformer oil and of gas-saturated oil on gap length for a point-sphere electrode system has been studied for the two polarities of the point. The effects of anodization of the sphere electrode on the breakdown voltage against gap characteristics have also been examined.

Enhanced heat flux in non-uniform electric fields

Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1973
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. This enhancement of the heat flux was much larger in a polar, slightly conducting liquid than in a practically ...
