Abstract Compared with the conventional flow control technology, surface dielectric barrier discharge (SDBD) has a great application prospect due to its advantages of fast response speed, small volume, flexible control position and low cost. In this paper, SDBD discharge experiments were carried out respectively under different voltage amplitudes and frequencies. Using Schlieren diagnostic technique, a systematic comparative analysis of induced airflow under different voltage amplitudes and frequencies was conducted. Here, pixel intensity integral method was used to deduce the velocity distribution of airflow induced by SDBD. Meanwhile, the influences of voltage amplitude and frequency on the induced airflow were analyzed qualitatively. The experimental results reveal that electrical power consumption of SDBD has an exponential relationship with voltage amplitude approximately, and a linear relationship with frequency approximately. As voltage amplitude and frequency increase, the length of the induced airflow tends to be in stable after increasing. In the longitudinal direction, the velocity distribution of the induced airflow shows a trend of increasing first and then decreasing to zero, and its maximum velocity increases with the increasing of voltage amplitude and frequency. Under different voltage amplitudes and frequencies, almost all the induced airflow velocity curves reach the maximum at 0.2mm above the medium surface and hardly vary with the changes of voltage amplitude and frequency.
