The Effect of Ultrasound on Hollow-Needle to Plate Electrical Discharge

Popis výsledku v původním jazyce

The effect of ultrasound standing waves at a frequency of 20.3 kHz on hollow-needle to plate electrical discharge enhanced by the flow of air through the needle is described. It was found that the suitable application of ultrasound increases discharge volume in cylindrical one wavelength ultrasonic resonator excited by solid piston with only a slightly smaller diameter than the resonator diameter. This discharge-spread is connected with radial pressure distribution as a result of ultrasound interactionwith the airflow from the needle. Efficient mixing in infinitesimal layer of the air created along vibrating electrode and other complex processes, which are caused by electrical and aerodynamic interactions can be used for environmental applications such as production of ozone, VOC decomposition and de-NOx processes enhancement.
