An approach for modeling the space charge density and the electric field distribution in electrostatic precipitators is presented. Two numerical techniques are used iteratively until a self-consistent solution is obtained: the boundary element method, for evaluation of the electric potential, and the characteristic method, determining the charge… (More)

In this paper, the electrohydrodynamic (EHD) flow in a single wire-plate electrostatic precipitator has been analyzed numerically by employing a hybrid Finite-Element Method-Method of Characteristics numerical algorithm and the commercial computational fluid dynamic software FLUENT6.2. Parameters defining both the electric and the flow fields were… (More)

We report a method to initiate and investigate electrical discharges of ambient air/water molecules in a nanometer-sized gap. Our methodology is based on a typical atomic force microscopy (AFM) setup, in which a cylinder discharge gap of < or =5 nm could be configured between the AFM probe and substrate. We observed highly localized stochastic… (More)

This paper presents the numerical study of the effect of electrohydrodynamic (EHD) flow on corona discharge in a pin-plate system in compressed air (pressures of 1-60 atm). The coupled electric and gas flow fields were simultaneously solved by using the commercial CFD FLUENT software. A hybrid numerical algorithm based on the boundary-element method, the… (More)

In this paper, a numerical algorithm for the simulation of the dynamic corona discharge in air is proposed assuming single-species charge carriers. The simulation results show the behavior of corona current and space-charge density under two waveforms of the applied voltage: step and pulse. The electric field is calculated by means of the finite-element… (More)

In this paper, a new 2-D model is presented for numerical simulation of Trichel pulses in a point-plane configuration. Both radial and axial components of the electric field are considered and it is assumed that three ionic species exist in the air gap: electrons, and positive and negative oxygen ions. The Poisson equation is solved for electric field… (More)

This paper presents a new dynamic model for the negative corona discharge in the point-plane geometry. The hybrid boundary-element-finite-element method technique is used to calculate the electric-field parameters, and the method of characteristics is employed for the charge-transport prediction. The simulation results show the charge-density distributions… (More)

The effect of airflow, including the electrohydrodynamic (EHD) flow produced by the electric corona discharge, and the flow generated externally on the corona discharge has been investigated numerically in this paper. Contrary to the common assumption that the corona discharge and the EHD flow can be decoupled by neglecting the convection term in the… (More)

AC electroosmotic pumping of fluids in a microchannel with two thin coplanar electrodes, deposited on one dielectric wall and placed in an aqueous solution, is studied in this paper. Two different numerical formulations are compared. In the first one, the transport equations (mass, molar, and momentum balances) for the ion concentration and the Poisson… (More)

In the present paper, a single-stage axisymmetric conduction micropump in the vertical configuration has been proposed. This micropump consists of four components: high voltage ring electrode, grounded disk-shaped electrode, insulator spacer, and inlet/outlet ports. The high-voltage electrode and grounded electrode of the device were patterned on the two… (More)
