三电极合成射流激励器电极布局与电源系统的匹配特性
Arrangement of Three-electrode Synthetic Jet Actuator and Its Matching Characteristics with Power System
摘要
Abstract
In order to increase the discharge intensity and stability of synthetic jet actuator,we investigated the three-electrode actuator and its discharge characteristics by using DC power supply and different trigger power supply.Moreover,we proposed the design criteria and optimized the arrangement of the three electrodes.The results show that as the rise time of the nanosecond pulse power supply is close to the breakdown delay time,the voltage cross the anode channel and cathode channel between the anode electrode and trigger electrode & cathode electrode and trigger electrode can achieve the breakdown voltage simutaneously when the two discharge channels form.When the rise time of the voltage slows down to microsecond,the voltage across the two channels cannot rise to the breakdown voltage simutaneously.At this time,if proper DC voltage is taken,there will be a delay time between formations of the two discharge channels.Above all,the channel distance and the adjustable channel range under stable discharge are determined by both trigger power supply and DC power supply.Nanosecond pulse power and high DC voltage can markedly increase the maximum discharge distance and the discharge stabilization.The largest discharge distance by μs pulse power and 4 kV DC power is 7.5 mm,while 10mm by ns pulse power & 0 kV DC power and 17.5 mm by ns pulse power &-4 kV DC power.关键词
