Abstract

The diffusion of charged aerosol particles from the flow to an isolated spherical collector under the influence of an electrostatic field is studied numerically. The dust concentration in the diffusional layer surrounding the sphere is calculated for an electric field aligned with the flow direction, opposite to it and transverse to the flow. The dimensionless mass transfer coefficient is evaluated for a wide range of electrostatic field intensities. The Sherwood numbers for the various electrostatic field orientations are compared with available analytical solutions.
