Definitions
- WO 2013/165242 A1 discloses a fluid displacement device configured to generate flow within a fluid.
- the fluid displacement device includes an airflow channel having an interior surface configured to receive fluid flow.
- a number of corona electrodes are disposed in the air flow passage, each of the corona electrodes comprising an elongate body having a distal end and a proximal end. The distal end is provided with a tip structure configured to create a corona discharge.
- a non-corona electrode is located downstream of the corona electrodes, the tips of the corona electrodes are at a predefined distance from the non-corona electrode, and the proximal end meets the inner surface of the air flow channel at a greater distance from the non-corona electrode is than the predefined distance.
