Summary:The transport of pre-charged particles in a wire—plate precipitator in turbulent flow is investigated by numerical solution of the convective diffusion equation. For ease of computation the high voltage wire electrodes are replaced by strip electrodes giving essentially the same potential distribution. It is shown that for equivalent values of the Deutsch and Peclet numbers, the efficiency of the wire—plate system agrees closely with that of a plate—plate system, provided the comparison is made on the basis of equal values of the space-averaged field at the collector. The study does not include corona charging as normally encountered.
