Mathematical Modeling of Double-Stage Electrostatic Precipitators Based on a Modified Eulerian Approach
A new mathematical model has been developed to predict the performance of a double-stage electrostatic precipitator. This model is based on the Eulerian approach for particle dispersion taking into account the particle size distribution. In this model, by calculating the frequency size distribution of particles and particle concentration distribution simultaneously through a modified particle dispersion equation, the CPU time for solving the governing equations has been reduced significantly. In order to evaluate velocity distribution of the fluid, the k— turbulent model, including the effect of electrical body force, has been used. Also, in this model the electric field was calculated by solving Maxwell's equation and including particle charge effect on electric field distribution. The results from the model have been compared with the experimental data of Leonard (1982). This comparison shows good agreement between calculated results and experimental data.
