电压波形对介质阻挡等离子体放电特性和体积力的影响
Influence of Voltage Waveform on Discharge and Thrust of Dielectric Barrier Discharge Plasma Actuator
摘要
Abstract
For the dielectric barrier discharge plasma actuator (DBDPA),both the discharge and the actuation performance will be influenced by the driving voltage waveforms.The investigation was based on the classic DBDPA and its discharge in static atmosphere driven by several voltage forms including sine,symmetry triangle,positive and negative ramp,and 25％,50％,75％ duty-cycle square.By the electronic balance and oscilloscope probe measurement,the thrust,the electric current,and the voltage signal were acquired.The features of the cimuit current and the microdischarge current pulses were analyzed,the discharge power was obtained by Lissajous figure,and the deposited surface charge influencing the threshold voltage of discharge was discussed preliminarily.The results reveal that the voltage slew rate depending on the voltage waveform is the main factor affecting the circuit current and the microdischarge current pulses.The threshold voltage of discharge is turned down and the ignition of plasma discharge is shifted to an earlier date by the virtual electrode formed by deposited surface charge which can reinforce the electric field between electrodes when the polarity of exposed electrode is changed.Both the time-averaged thrust and discharge power produced by the square wave driving voltage are relatively larger,the ones produced by the sine wave are smnaller,and the relatively smallest ones are produced by the remaining waveforms.Of all,both the maximum time-averaged thrust and the maximum discharge power are produced by the square wave with 50％ duty cycle.关键词
