抄録

A numerical simulation is conducted to investigate the effect of the ionic wind and the effect of the electro-hydro-dynamic (EHD) flow field on the collection efficiency of a duct type electrostatic precipitator for the case of submicron size dust particles. The calculations for the ionic flow field and the EHD flow field are carried out by the Finite Element Method. Re- sults show that the flow pattern of gas in the EHD flow field depends on the EHD number. The collection efficiencies are at minimum values when the particle diameter is about 0.3 μm, both without and with the ionic wind. The collection efficiency is reduced considerably in the EHD flow field. An increase in the EHD number does not always mean that the collection efficiency will increase uniformly. The collection efficiency curves have maximum values at the EHD numbers which range within the limits in the case that the particle size is from 0.05 to 0.30 μm approximately.
