Dynamic Flow Sheet Simulation of an Electrostatic Precipitator

Flow Distribution inside an Electrostatic Precipitator: Effects of Uniform and Variable Porosity of Perforated Plate

This paper presents a numerical flow model applied to a 3D geometry of an electrostatic precipitator (ESP). The flow simulation is performed by using the computational fluid dynamics (CFD) code FLUENT. Realizable k-ε model for turbulence condition inside the ESP is applied. In the simulation, the perforated plates are modeled as thin porous media of finite thickness with directional permeabilit...

Power Electronic Modelling and Emulation of an Electrostatic Precipitator

In this paper a power electronic emulation of an electrostatic precipitator is presented. Precipitator power supplies can be tested under real power and operating conditions up to 200 kVA. Energy consumption of the system is very low, because the energy which is drawn by the emulation converter is fed back into the power grid. Therefore, just the power losses have to be provided by the grid. It...

Removal of Serratia marcescens aerosols using an electrostatic precipitator.

We characterized the efficacy of an electrostatic precipitator (ESP) air-cleaner in reducing the concentration of Serratia marcescens in an enclosed space. We used an experimental room (4.5 x 3 x 2.9 m) in which electrostatic aircleaners were located. Two air-cleaners enhanced the equivalent ventilation rates in the chamber by about 3.3 air changes per hour (ACH) over the 2 ACH provided by the ...

Modern High-Voltage Control of an Electrostatic Precipitator

Laser flow visualization and velocity fields by particle image velocimetry in an electrostatic precipitator model

Although improving electrostatic precipitator (ESP) collection of fine particles (micron and submicron sizes) remains of interest, it is not yet clear whether the turbulent flow patterns caused by the presence of electric field and charge in ESPs advance or deteriorate fine particle precipitation process. In this paper, results of the laser flow visualization and Particle Image Velocimetry (PIV...
