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 ...

Thermal and electrohydrodynamic plumes: a compartive study
(AIP Publishing, 1996)
This paper deals with self similar thermal and electrohydrodynamic (EHD) plumes. The former arises from hot lines or points, whereas the latter arises when sharp metallic contours submerged in non conducting liquids ...

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 ...

The Lorentz force on ions in membrane channels of neurons as a mechanism for transcranial static magnetic stimulation
(Taylor & Francis, 2020)
Transcranial static magnetic stimulation is a novel noninvasive method of reduction of the cortical excitability in certain neurological diseases that makes use of static magnetic fields generated by permanent magnets. By ...

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 ...

Dynamics of EHD Laminar Plumes: scaling analysis and integral model
(AIP Publishing, 2000)
In this paper electrohydrodynamic (EHD) plumes are examined in the region far from the injecting electrode and the collector plate, for both two-dimensional and axisymmetric geometries. The relative importance of the ...

Numerical analysis of electro-convection in dielectric liquids with residual conductivity
(AIP Publishing, 2022)
Injection-induced electro-convection (EC) of dielectric liquids is a fundamental problem in electrohydrodynamics. However, most previous studies with this type of EC assume that the liquid is perfectly insulating. By ...

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 ...
