Numerical simulation for particle-trajectory in a spray charging precipitator

The trajectory equation of particles was put forward with Lagrangian approach on the basis of Newton law. The mathematical model of a single particle-trajectory was established. The modeling software box was programmed based on MATLAB, by which the mathematical model was simulated to make it visual. The simulation study points out that the electrostatic power is considered as the major factor to collect the small particles of low speed and the effect of inertia and the hold-up process are important to the removal of the particles. The software box is proved reasonable and applicable in design.
