Jet Vectoring and Vorticity Generation Using Plasma Actuators

Bolitho, Michael
The current study examines the use of plasma actuators as flow control devices, including synthetic jet actuators, jet vectoring, and vortex generation. The study of the plasma actuators applied to flat plates is conducted in quiescent conditions, as well as in the wind tunnel. There are two arrangements of plasma actuators investigated, one of which consists of an inner circular electrode embedded under a dielectric material and an outer annular electrode exposed to the atmosphere, and is used to create flow structures similar to that of a conventional synthetic jet actuator. The other arrangement is made up of a single linear electrode embedded within a dielectric material with a linear electrode on either side exposed to the atmosphere, and is used to create vectored jets and generate streamwise vortices.
