Modelling and simulation of thunderstorm electric field
International Journal of Modelling, Identification and Control, 2013As the complexities and difficulties of the direct sounding experiment, the paper conducts a calculated and simulating research on the electric field, which is generated by thunderstorm. In accordance with the data of the detection of an air electric field, the authors established China’s inland plateau thunderstorm charge distribution model by ...

Electric Circuit Model for Electrical Field Flow Fractionation
Analytical Chemistry, 2006In electrical field flow fractionation (EFFF or ElFFF), an electric potential is applied across a narrow gap filled with a weak electrolyte fluid. Charge buildup at the two poles (electrodes) and the formation of an electric double layer shields the channel, making the effective field in the bulk fluid very weak.

A model of the auroral electric field
Journal of Geophysical Research: Space Physics, 1979A model is constructed from a self‐consistent solution of the Vlasov‐Maxwell equations. The model has certain properties in common with auroral arcs. A pair of electric fields similar to the auroral electric fields is shown to be inherent to the electron current sheet in the model.

Electric field variability associated with the Millstone Hill electric field model
Journal of Geophysical Research: Space Physics, 2000Joule heating that is generated at high latitudes in the thermosphere because of the magnetospherically imposed electric potential is proportional to the average of the square of the electric field (E field). Most theoretical Joule heating computations use only average electric fields, resulting in heating that is proportional to the square of the ...

Modelling a droplet moving in an electric field
Mathematics and Computers in Simulation, 2005If a droplet is put into a homogeneous electric field, the droplet disturbs the field, the field effects a concentration of charge at the droplet surface and the droplet deforms due to the force density which the disturbed electric field causes on the electric charge. In this case, the droplet suffers a pure deformation without any translation.

An electrokinetic model of drop deformation in an electric field
Journal of Fluid Mechanics, 2002An electrokinetic model is proposed to describe a slight drop deformation which is induced by a weak external electric field. The fluids forming the system are considered Newtonian incompressible dielectric liquids containing free electric charge carriers.

Electric fields and proliferation in a chronic wound model
Bioelectromagnetics, 1996A wound model for decubitus and leg ulcers consisting of human dermal fibroblasts in type I collagen dermal "equivalent" matrix (DEM) was exposed in vitro to electric fields similar to postulated endogenous fields in wounds. After an 8-10 day maturation period, conductivity of DEM samples was determined.

Mathematical Models of Electric Fields of Electric Transmission Lines
2021The chapter contains analytical expressions for calculating strength of the electric and magnetic fields of the objects of the energy system. Such mathematical models are necessary to create a dependence of the behavior of these fields for various operating modes.

Analytical Model for Electrical Field at Ultrathin Field Emitter
2021The potential barrier near the apex of an ultrathin edge field emitter is defined using an analytical model. It is used to simulate electron tunnelling from the emitter numerically. The results show that for an ultrathin emitter, the traditional approximation of a uniform field near the edge is inappropriate.
