The characteristics of turbulent deposition of charged particles in a plate-plate electrostatic precipitator (ESP) are analyzed by the Lagrangian simulation method which uses the concept of time series analysis for the particle motion in a turbulent flow field. With the advantage of the Lagrangian method, several important parameters are taken into account such as the effect of nonuniform diffusivity on the particle motion and the effects of particle inertia including the crossing trajectory effect, boundary layer trapping and the lift force near the wall. Collection efficiencies are obtained without any simplified treatment for a wide range of Peclet number (Pe*) of interest, where it is found that the collection efficiency is mainly the function of Pe* and Deutsch number, and the dependency on particle relaxation time is negligible in the range about Pe* > 0.1. Moreover, the characteristics of deposition at the intermediate Pe* is analyzed clearly, where both the diffusion and migration by external force play an important role on the deposition. |
