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 ...

On two-dimensional finite amplitude electro-convection in a dielectric liquid induced by a strong unipolar injection
(Elsevier, 2015)
The hydrodynamic stability of a dielectric liquid subjected to strong unipolar injection is numerically investigated. We determined the linear criterion Tc (T being the electric Rayleigh number) and finite amplitude one ...

Electroconvection in a dielectric liquid between two concentric half-cylinders with rigid walls: Linear and nonlinear analysis
(American Physical Society, 2018)
We study the linear stability and nonlinear behavior of the electroconvection between two concentric halfcylinders with no-slip conditions on all boundaries. The no-slip condition makes impossible to apply the standard modal ...

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 ...

Onset of convection in a finite two-dimensional container due to unipolar injection of ions
(American Physical Society, 2013)
This work addresses the stability of a two-dimensional plane layer of a dielectric liquid enclosed in wall bounded cavities of different aspect ratios and subjected to unipolar injection of ions. Numerical simulations have ...

Numerical Study of a Plane Poiseuille Channel Flow of a Dielectric Liquid Subjected to Unipolar Injection
(Institute of Electrical and Electronics Engineers (IEEE), 2015)
In this paper, the interaction between a plane Poiseuille channel flow and an electroconvective movement induced by the electric field is numerically investigated. A flow is generated by an inlet parabolic profile in a ...

Finite amplitude electroconvection induced by strong unipolar injection between two coaxial cylinders
(AIP Publishing, 2014)
We perform a theoretical and numerical study of the Coulomb-driven electroconvection flow of a dielectric liquid between two coaxial cylinders. The specific case where the inner to outer diameter ratio is 0.5 is analyzed. ...

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 ...
