Title: Flow Control at Subsonic Speeds using Serpentine Plasma Actuators
Abstract: The use of plasma actuators for flow control applications is fast becoming the subject of many research campaigns. A drawback of this technique is the relatively low flow speeds that the plasma induced jet exhibits. One method of enhancing the influence of such actuators, is to devise novel actuator configurations that despite their low induced speeds still have the ability to considerably manipulate the flow characteristics. The objective of the current study is to apply the newly developed serpentine plasma actuator to a standard backwards facing step model in a low-speed wind tunnel operating at 15m/s. The influence of the actuator on the separated shear layer is examined using PIV. The results show that due to the three-dimensional flow induced by the actuator, the shear layer exhibits different characteristics along the span wise direction. It is believed that using plasma actuators with three-dimensional flow characteristics has the ability to create greater control authority at the relatively low plasma induced velocities.
