Simple frigate shape plasma flow control

Bardera Mora, R., Conesa, A., Lozano, I. 2016. Simple frigate shape plasma flow control. Proceedings of the Institution of Mechanical Engineers part G-Journal of Aerospace Engineering 230, 14, 2693-2699 DOI: 10.1177/0954410016630333

This experimental investigation presents a new active flow control technique based on plasma actuators applied to a backward facing step whose structure is similar to that formed by the hangar and flight deck of small naval vessels. These experiments were carried out by testing a simple frigate shape model settled at 0 degrees wind over deck in a low-speed wind tunnel. Two different configurations of dielectric barrier discharge plasma actuator have been used to modify the flow downstream of the step. Results obtained investigating the flow by particle image velocimetry prove the capacity of plasma actuators by reducing instabilities and turbulence over the simple frigate shape model.
