Download or read book Three dimensional Modeling of Electrostatic Precipitator Using Hybrid Finite Element flux Corrected Transport Technique written by Niloofar Farnoosh and published by . This book was released on 2011 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the results of a three-dimensional simulation of the entire precipitation process inside a single-electrode one-stage electrostatic precipitator (ESP). The model was designed to predict the motion of ions, gas and solid particles. The precipitator consists of two parallel grounded collecting plates with a corona electrode mounted at the center, parallel to the plates and excited with a high dc voltage. The complex mutual interaction between the three coexisting phenomena of electrostatic field, fluid dynamics and the particulate transport, which affect the ESP process, were taken into account in all the simulations. The electrostatic field and ionic space charge density due to corona discharge were computed by numerically solving Poisson and current continuity equations, using a hybrid Finite Element (FEM) - Flux Corrected Transport (FCT) method. The detailed numerical approach and simulation procedure is discussed and applied throughout the thesis. Calculations of the gas flow were carried out by solving the Reynolds-averaged Navier-Stokes equations using the commercial FLUENT 6.2 software, which is based on the Finite Volume Method (FVM). The turbulence effect was included by using the k- model included in FLUENT. An additional source term was added to the gas flow equation to include the effect of the electric field, obtained by solving a coupled system of the electric field and charge transport equations, using the User-Defined-Function (UDF) feature of FLUENT. The particle phase was simulated using a Lagrangian-type Discrete Random Walk (DRW) model, where a large number of particles charged by combined field and diffusion charging mechanisms was traced with their motion affected by electrostatic and aerodynamic forces in turbulent flow using the Discrete Phase Model (DPM) and programming UDFs in FLUENT. The airflow patterns under the influence of electrohydrodynamic (EHD) secondary flow and external flows, particle charging and deposition along the channel, and ESP performance in removal of submicron particulates were compared for smooth and spiked discharge electrode configurations in the parallel plate precipitator assuming various particle concentrations at the inlet. Finally, a laboratory scale wire-cylinder ESP to collect conductive submicron diesel particles was modeled. The influence of different inlet gas velocities and excitation voltages on the particle migration velocity and precipitation performance were investigated. In some cases, the simulation results were compared with the existing experimental data published in literature.

Download or read book High Temperature Electrostatic Precipitation Fundamentals Phenomena and Feasibility written by Patrick Bürger and published by Cuvillier Verlag. This book was released on 2023-07-03 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Particle separation from hot gases is a challenging task, especially for nanoparticles. Therefore, it is usually avoided by quenching the hot gas to conduct particle separation at a more convenient temperature. In these cases, valuable high-caloric heat is either not utilized at all or only inefficiently because of particle deposition on the heat exchanger surfaces. Valuable potential is thus wasted, as high-temperature processes are already an essential part of many industries and become increasingly relevant for other industrial sectors (e.g., pyrolytic processes in the circular economy). To reduce operating costs and environmental impact, the efficient use of resources (especially fossil fuels) is an absolute necessity. To tackle this pending problem, the concept of high-temperature electrostatic precipitation is investigated in this doctoral thesis. In an electrostatic precipitator, particles are charged by charge carriers produced in a corona discharge near the discharge electrode. Charged particles migrate due to the electric field and subsequently precipitate onto the collection electrode. This doctoral thesis clearly demonstrates the feasibility of nanoparticle removal from hot gases at up to 1073 K (800 °C) using electrostatic precipitation while presenting novel insights into the charge carrier properties and their distribution, the influence of thermionic emission on the operation of electrostatic precipitators, and the fundamentals of particle charging at high temperatures.

Available in PDF, EPUB and Kindle. Book excerpt: Electrostatic precipitators (ESP) are used extensively for removing particulates from a gas flow by charging the particles and then removing them in the presence of an electric field. Traditional ESP designs use the walls of the flow channel as the grounded collection surface. The objective of this present study is to evaluate an ESP configuration in which an array of cylinders in a crossflow configuration is used as grounded collection surfaces. A numerical approach using ANSYS Fluent computational fluid dynamics (CFD) software was used to build a two-dimensional model for the gas flow and particulate capture. The model uses governing equations of fluid mechanics and electric fields to determine the fluid flow profiles, the charging of the particles, and the transport of the charged particles to the surfaces of grounded collection cylinders. The results of this study show that the particle collection is strongly influenced by two opposing phenomena, both of which are determined by the geometrical arrangement of the array of cylinders. The first phenomenon is the generation of turbulence regions behind the collector rows due to the cylinders obstructing the flow, which can enhance particulate capture downstream. The second is the shielding of the electric field by the cylinders which reduces the particulate transport to the grounded cylinder surfaces in the region separating the collector rows.

Download or read book Applied Electrostatic Precipitation written by K.R. Parker and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many industrial, power generation and chemical processes produce unwanted fine particulate material as a consequence of their operation. Electrostatic precipitation is a highly efficient method of removing entrained particulate contaminants from exhaust gases and is extensively used in these industries to limit particulate emissions. New legislation aimed at improving the environment by further limiting these discharges has resulted in the technique undergoing considerable development over the past decade, to the point where it has become the method of choice, over a wide range of applications, for limiting particulate discharges. In this new book, the editor has brought together an international team of contributors, mainly industrialists and consultants, to produce an authorative and practical guide to electrostatic precipitation. This book is of interest to all those in process industries or power generation and to academics concerned with gas cleaning and environmental issues.

This book was released on 1998-11-20 with total page 1169 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first volume of CFD Review was published in 1995. The purpose of this new publication is to present comprehensive surveys and review articles which provide up-to-date information about recent progress in computational fluid dynamics, on a regular basis. Because of the multidisciplinary nature of CFD, it is difficult to cope with all the important developments in related areas. There are at least ten regular international conferences dealing with different aspects of CFD.It is a real challenge to keep up with all these activities and to be aware of essential and fundamental contributions in these areas. It is hoped that CFD Review will help in this regard by covering the state-of-the-art in this field.The present book contains sixty-two articles written by authors from the US, Europe, Japan and China, covering the main aspects of CFD. There are five sections: general topics, numerical methods, flow physics, interdisciplinary applications, parallel computation and flow visualization. The section on numerical methods includes grids, schemes and solvers, while that on flow physics includes incompressible and compressible flows, hypersonics and gas kinetics as well as transition and turbulence. This book should be useful to all researchers in this fast-developing field.
