Charge injection enhanced natural convection heat transfer in horizontal concentric annuli filled with a dielectric liquid
(Elsevier, 2016)
The natural convection heat transfer in a highly insulating liquid contained between two horizontal concentric cylinders is shown by two-dimensional numerical simulations to be noticeably enhanced by imposing a direct ...

Instability in a non-ohmic/ohmic fluid interface under a perpendicular electric field and unipolar injection
(American Institute of Physics, 2002)
We set the equations for the linear electrohydrodynamic instability of an interface between two fluids, subjected to a perpendicular field and a unipolar charge injection. One of the fluids is modeled as being in non-ohmic ...

Numerical simulation of EHD flows using Discontinuous Galerkin Finite Element methods
(Elsevier, 2013)
The aim of this paper is to explore the capability of Discontinuous Galerkin Finite Element methods to solve numerically the charge transport equation in EHD convective flows, in both strong and weak injection regimes. ...

Instability of an interface between air and a low conducting liquid subjected to charge injection
(American Institute of Physics, 2006)
We study the linear stability of an interface between air and a low conducting liquid in the presence of unipolar injection of charge. As a consequence of charge injection, a volume charge density builds up in the air gap ...

Numerical evaluation of heat transfer enhancement due to annular electroconvection induced by injection in a dielectric liquid
(Institute of Electrical and Electronics Engineers (IEEE), 2016)
Two-dimensional numerical simulations are carried out to evaluate the enhancement of natural convection heat transfer in a dielectric liquid resulting from injection induced annular electro-convection. The liquid is ...

Complex flow patterns at the onset of annular electroconvection in a dielectric liquid subjected to an arbitrary unipolar injection
(Institute of Electrical and Electronics Engineers (IEEE), 2015)
We numerically investigated the annular electroconvection that takes place in a dielectric liquid lying between two concentric cylinder electrodes. A uniform injection of arbitrary strengths either from the inner or outer ...

Electrohydrodynamic linear stability analysis of dielectric liquids subjected to unipolar injection in a rectangular enclosure with rigid sidewalls
(Cambridge University Press, 2014)
We investigate the linear stability threshold of a dielectric liquid subjected to unipolar injection in a 2D rectangular enclosure with rigid boundaries. A finite element formulation transforms the set of linear partial ...
