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 ...

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 ...

Coulomb-driven flow of a dielectric liquid subject to charge injection by a sharp electrode
(AIP Publishing, 1999)
Injection of charge by a sharp electrode into a surrounding dielectric liquid leads to Coulomb forces that set the liquid into motion. An analysis is presented of this motion in a small region around the edge of the ...

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 ...
