Electric Field Distribution of Wire-Duct Electrostatic Precipitator using FDM and MATLAP

Fadhil Khaddam Fuliful

Abstract: This paper presents the electric field distribution in three-dimension (3-D) of duct-type electrostatic precipitator (ESP) for different values of geometrical parameters using a new program implemented in MATLAB. Poisson's and Current Continuity equations are solved simultaneously using the Finite Difference Method (FDM) with Dirichlet boundary conditions and programmed in MATLAB. The effects of wire-plate spacing and half wire-wire spacing on the electric field distribution are evaluated. In the present study the software's is promising for getting accuracy results due to less time of executing and increasing the point's number in the mesh of problem domain which is explained electric field distribution of the configuration. Also reducing energy consume for new design (applied voltage of wire-discharge is 60 kV in case of wire-plate distance equal 10 cm), 3-D results which have been obtained through their implementation in computer programs are better than the results of FDM or FEM techniques when it use without combined with other techniques. Finally some conclusions are viable in design ESP.
