3-D numerical analysis of EHD turbulent flow and mono-disperse charged particle transport and collection in a wire-plate ESP

The present study attempts to develop a detailed numerical approach and a simulation procedure to predict the motion of gas ions and particles inside a simple parallel plate channel containing a single corona wire A hybrid Finite Element (FEM)-Flux Corrected transport (FCT)-Finite Volume (FVM) method is used the FEM-FCT numerical algorithm is applied for modeling the steady-state corona discharge while the turbulent gas flow and the particle motion under electrostatic forces are modeled using the commercial CFD code FLUENT Calculations for the gas flow are carried out by solving the Reynolds-averaged Navier-Stokes equations and turbulence is modeled using the kappa-epsilon turbulence model An additional source term is added to the gas flow equation to Include the effect of the electric field obtained by solving a coupled system of the electric field and charge transport equations using User-Defined Functions (UDFs) The particle phase is simulated based on the Lagrangian approach where a large number of particles is traced with their motion affected by the gas flow and electrostatic forces using the Discrete Phase Model (DPM) in FLUENT The developed model is useful to gain insight into the particle collection phenomena that take place inside an ESP (C) 2010 Elsevier BV All rights reserved
