Three-Dimensional Modeling Of Electrostatic Precipitator Using Hybrid Finite Element - Flux Corrected Transport Technique, Niloofar Farnoosh
Three-Dimensional Modeling Of Electrostatic Precipitator Using Hybrid Finite Element - Flux Corrected Transport Technique, Niloofar Farnoosh
Electronic Thesis and Dissertation Repository
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 …
Fem-Fct Based Dynamic Simulation Of Trichel Pulse Corona Discharge In Point-Plane Configuration, Paria Sattari
Fem-Fct Based Dynamic Simulation Of Trichel Pulse Corona Discharge In Point-Plane Configuration, Paria Sattari
Electronic Thesis and Dissertation Repository
In this thesis, a new two-dimensional numerical solver is presented for the dynamic simulation of the Trichel pulse regime of negative corona discharge in point-plane configuration. The goal of this thesis is to simulate the corona discharge phenomenon and to improve the existing models so that the results have an acceptable compatibility with the experimentally obtained data. The numerical technique used in this thesis is a combination of Finite Element Method (FEM) and Flux Corrected Transport (FCT). These techniques are proved to be the best techniques, presented so far for solving the nonlinear hyperbolic equations that simulate corona discharge phenomenon. …
