“…It is similar to that used in the validation model but with neglecting the collecting stripe thickness and increasing its length, b, to 10 mm, whereas the channel length is reduced by 20 mm. The same modelling parameters used in the validation model are adopted, including the corona wire diameter, which is recommended in compact EHD blowers to create a strong electric field using low levels of operating voltage [31,42]. The numerical analysis is established to explore the impact of several design parameters on the EHD air blower efficiency and optimize its geometry based on ranges of fixed powers and applied positive voltages.…”

“…The results showed that the optimized EHD blower was able to increase the heat transfer by more than double compared to free convection. This study was later extended by Rashkovan et al [31] by reducing the emitter wire diameter to 0.2 mm in order to enhance the electric field strength, aiming to develop the EHD air blower and improve its performance. Based on the highest heat transfer coefficient achieved, the optimum configuration was obtained by using a corona wire located between two parallel collecting wings, where the wire is collinear with the adjacent ends of the collecting plate wings, creating an angle of 55.5 o with their far ends.…”

The airflow induced by corona discharge is called ionic wind, and it could be applied for flow control with its advantages of no moving parts and simple construction. This paper introduces ionic wind characteristics on a flat plate by discharge voltage of 5 kV. A dc corona discharge electrode setup was designed to modify the airflow on a flat plate. The electrode configuration consisted of sharp pin electrode and grounded plate electrode. Weak light emission was observed at the tip of the pin electrode with energizing electrode system. The ionic wind velocity was measured with a hot wire anemometer (up to 2 m/s). Discharge diagnostics included emission spectra, discharge voltage, current, and power and ozone density.Index Terms-Active flow control, corona discharge, electrohydrodynamics (EHD) phenomenon, ionic wind, plasma actuator.

“…These properties of EHD gas pumps give rise to a variety of applications. However, all these applications require maximizing the flow velocity of the EHD gas pump [2,4], [13][14][15][16]. A higher gas flow velocity can be obtained by a positive corona discharge of a needle-to-mesh geometry [3][4]10].…”

A sliding discharge-type electrohydrodynamic (EHD) gas pump, utilizing a discrete saw-toothed-plate electrode as a discharge electrode instead of a smooth conventionalplate electrode, has been developed. The effect of the saw-toothed-plate electrode on the gas flow velocity and yield of flow generation of the EHD gas pump were investigated. It was observed that the EHD gas pump can generate a higher gas flow velocity and yield of flow generation than the same design EHD gas pump with the conventionalplate electrode. As a result, a peak gas flow velocity of V G =1.65 m/s from the EHD gas pump with the saw-toothed-plate electrode can be obtained for V P =12.0 kV, which is 2.39 times higher than that of V G =0.69 m/s of the same design EHD gas pump with the conventional-plate electrode. With the saw-toothed-plate electrode, the yield of flow generation of Y G =0.435 m/Ws can be obtained for V=8.0 kV, which is 4.53 times higher than that of the same design EHD gas pump with the conventional-plate electrode of Y G =0.096 m/Ws. These enhancements are due to the effect of the saw-toothed-plate electrode being utilized instead of the conventional-plate electrode.Index Terms -EHD gas pump, sliding discharge, saw-toothed-plate discharge electrode, conventional-plate discharge electrode, gas flow velocity.
