Inertia effect on deposition of charged particles in a parallel-plate channel

Abstract

The effect of inertia forces on the deposition of highly charged fine particles of sizes less than 20 μm in a parallel-plate channel has been analyzed numerically for uniform and fully-developed flows. The deposition is primarily due to space charge alone and the image and gravity forces are not included in the analysis. A charge—inertia parameter n (ranging from 0 to 1) was defined to characterize the flow deposition phenomena. It was found that for n less than 0.1 the effect of inertia forces may be neglected and that the fraction of deposition near the entrance of the channel deviates substantially from the result neglecting the inertia effect.
