The nonuniform corona discharge in the wire-plate electrostatic precipitator results in a rotational electric body force which is a source of large-scale secondav flows and turbulence within the flow channel. The electrically induced flow causes large increases in diffusivities detrimental to the particle collection process. Since the electrode geometry and the structure of the corona discharge define the magnitude and character of the electric body force, it is theoretically possible to design a discharge electrode which minimizes electrohydrodynamic flow disturbances. As a first step in this direction, a novel planar electrode design in which electrical discharges are configured to reduce the inhomogeneities of the electric body force is experimentally studied in a negative polar

Reports on the radial distribution of the current density produced by a corona triode using the metallic point placed in the axis of insulating tubing. The experimental results are fitted with a model, accounting for the space charge in the grid-to-plate gap, and the corona wind. For a small grid bias, the simulation yields a current-density distribution similar to that of the corona-wind velocity. Using a proper feedback control of the grid bias, the charging current can be kept constant, and the resulting charge distribution is almost uniform. The evolutions of the surface charge patterns obtained with and without feedback control of the grid bias are compared.
