Electrohydrodynamic flow in a barbed plate electrostatic precipitator
The large scale secondary flows and turbulence induced by the inhomogeneous negative corona discharge in the conventional wire-plate precipitator are known to reduce collection efficiencies, particularly in applications with high mass loadings of fine particulates. Electrohydrodynamic theory suggests that a modification in electrode geometry is necessary to control the electrically induced flow. A plate-plate precipitator using a barbed plate discharge electrode is designed to provide a more uniform current density distribution. Electrical and fluid dynamic characteristics of four model barbed ...
