It is known that ionic wind is due to the flow of many ions in the corona discharging field. In complicated manner its force will act on the dust in the collecting field for an electrostatic precipitator. The purpose of experiment is to find the influences of the ionic wind on the collecting forces in the corona discharging field for the electrostatic precipitator. The one step of studies is to observe the ionic wind phenomena in the corona discharging field in atomospheric air. In this experiment, the ionic wind phenomena in the model of electrostatic precipitator was photographed by the schlieren method. The model-electrostatic precipitator was composed of one discharging wire and one plate as the collecting electrode. This discharging wire was heated by current because the variable density of air was to exist for this experimental method. The experimental results were shown by the schlieren photographs of the ionic wind phenomena, and the comparison of the ionic wind phenomena with the corona current was considered.
