Estimation the 3-D electrical characteristics of an electrostatic precipitator using FDM and MATLAB

Fadhil K. Fuliful


This paper used a new program implemented in MATLAB to calculate the electric potential, electric field and charge density distributions in three dimensions (3-D) of an electrostatic precipitator for wire-plate type, the principle of the program is Finite Difference Method (FDM) which is applied to solve Poisson’s equation and the relation between electric potential and electric field with suitable boundary conditions and programmed in MATLAB. In the present study the software's appears both accuracy results and the computation time required for solving the problem is less. Also the results obtained through their implementation in computer programs are better than FDM or FEM techniques when it use without combined of other technique.
