Investigation on the acceleration characteristic by plasma aerodynamic actuation

Experimental investigation and analysis on the acceleration characteristic by plasma aerodynamic actuation were performed while the ambient air was still. The induced airflow velocities were measured and analyzed with pitot tube and particle image velocimetry. The experimental conclusion shows that the acceleration characteristic changes to different extents while the actuation parameters (such as actuation voltage, actuation frequency and electrode numbers) change. The discussion on the acceleration mechanism by PIV results confirms that as an active flow control of aerocraft and power settings, plasma aerodynamic actuation has extensive research and application foreground.
