We propose Phase I and II efforts that will focus on turbomachinery flow control. Specifically, the present work will investigate active control in a high speed turbine flow. The flow control actuators will be Single Dielectric Barrier Discharge (SDBD), or "plasma actuators." The work will be primarily experimental, with a focus on realistic operating environments for investigating the efficacy of the actuators. The proposed measurements will be the first to utilize plasma flow control in an aerodynamically realistic LPT environment. The objective of the research will be to study the secondary flows in a modern low pressure turbine (LPT) environment, and use active flow control to provide enhanced aerodynamic and/or heat transfer characteristics by controlling the secondary flows through the nozzle and rotor sections of the turbine.
