Abstract :
To initiate an ionic induced flow within atmospheric air, the high voltages are applied to the atmosphere by the coronas, creating an ionic flow to a grounded collector or ring. In experiments with a focus on the viability of applying the ionic wind as a cooling mechanism, using a shallow ring as the grounded collector for the ionized air, it was found that there is a relationship between the size of the grounded ring and the velocity of the flow caused by the ionization from the electrodes, maintaining voltage as a constant, a smaller ring provides higher efficiencies, while larger rings provide higher flow rates at larger dynamic pressures. Further research is being conducted on the influence of multiple corona discharges on the velocity and the effective static pressure of ionic flows in air as well as combustible flows.
