COMPUTATION OF PARTICLE-TRANSPORT IN AN ELECTROSTATIC PRECIPITATOR

Two-dimensional turbulent gas now and particle trajectories under the influence of an electric field are calculated by using the commercial computational fluid dynamics (CFD) package, FLUENT, combined with a fi nite-volume solver for the electric field and ion charge. Particle cha rge is determined from local electric conditions and cell residence ti me. Particle charge density is evaluated hom the Lagrangian calculatio n of the particle motion. The effects of particulate space charge on t he electric field and current now are investigated.
