Measuring efficiency of positive and negative ionic wind devices for comparison to fans and blowers

A model for determining the unipolar ionic saturation current in parallel wire-cylinder electrodes during corona discharge

“…An experimentally verified mathematical model for determining the unipolar saturation current distribution over the cylinder's surface and the corresponding total saturation current limit in a wire-cylinder electrode configuration is being presented in this paper. Positive coronas have only been examined due to the fact that they are more stable and efficient for typical applications involving wire-cylinder electrode arrangements, such as ionic wind generators [20] or electrostatic separators [21]. Unipolar coronas contain ions of one sign only, which is the main reason for their extended use in electrostatic apparatus (precipitators, paint guns, separators etc.).…”

Basic Study on Flow Control by Using Plasma Actuator

“…This kinetic energy induced by the Coulomb force is known as the electrohydrodynamics (EHD) phenomenon [3], and direction of ionic wind is from a pin electrode to a plate one regardless of corona polarity. Ionic wind is also called EHD flow or electric wind [6], [7]. Ionic wind generator is known as plasma actuator [8], [9].…”

Numerical Analysis and Optimization of Miniature Electrohydrodynamic Air Blowers

“…Although the attempts to develop corona wind generation were made early, the most interesting investigations have been conducted over the last decade [27][28][29]. Based on performance of airflow generation, few studies have been performed to optimize the design geometry of EHD blowers in the absence of external bulk flow and without any integration between the collector electrode and heat exchange surface.…”
