Experimental studies of excitation parameters' influences on plasma EHD acceleration effect

Experimental studies on excitation parameters' influences on plasma EHD acceleration effect are carried out in quiescent air. Under fixed excitation frequency, the induced airflow velocity increases almost linearly when the excitation voltage increases; While under fixed excitation voltage, the induced airflow velocity doesn't increases linearly when the excitation frequency increases. In fact, it gets its maximum value under an optimal frequency. The results of the experiments can help to discover the mechanism of glow discharge plasma EHD, and to establish the foundation for the application of plasma flowing control.
