Abstract. In this paper, the motion of charged particles for incompressible flow in electrical field has been investigated. Two applications have been simulated and compared with experimental results. The first one is a simulation model for electric filter made of split type fiber. This simulation has been developed to study the filtration efficiency. The filter was assumed to be composed of rectangular fibers arranged in staggered array field. Single fiber efficiencies under various filtration conditions were calculated and compared with results obtained from semi-empirical expressions derived from experimental data. The second one is the numerical simulation of electrostatic powder painting. The purpose of this study was to understand the gas and particle flow fields inside a coating booth under given operating conditions and the effect of particle sizes on its trajectories. The continuous gas flow was calculated by solving Navier–Stokes equations including the standard k−ε turbulence. The discrete phase was modeled based on the Lagrangian approach. In both cases the flow field and the collection mechanisms were simulated using Fluent software. All results are in good agreement with experimental data.
