Plasma Actuators for Enhanced Wind Turbine Performance
Presentation will focus on a case study analysis performed on the use of Single Dielectric Barrier Discharge (SDBD) plasma actuators to enhance the energy capture of a 1.5 mega watts wind turbine. The object was to reduce the chord of the standard blade by 20 [percent for mass savings on the inboard portion of the rotor without a loss in performance. The reduced mass would then be added to increase the blade length. The motivation for this investigation comes from the fact that the rotor distribution mass with an approach proposed to increase the swept area of a wind turbine without increasing the rotor blade weight. Numerical investigations were conducted to investigate the use of plasma flow control in this rotor design concept. Active flow control, in the form of plasma actuator, was incorporated into the truncated rotor sections to recover the lost aerodynamic performance. Three reduced chord cases were examined through numerical flow simulations.
The cast study is just the first step towards the overall objective of applying a rigorous decision-based design optimization approach to the rotor geometry with active flow control, and to the total wind energy system in general.
Corke is the founding director of the Institute for Flow Physics and Control (FlowPAC), and the director of the Hessert Laboratory for Aerospace Research. He is internationally recognized for his research in the areas of fluid instabilities and transition to turbulence, control of turbulent boundary layers, flow visualization techniques and flow control.

Groups of high schoolers eagerly lined up Tuesday morning at Purdue University to test how well their handcrafted wind turbines would perform when stacked against the power of four fans. The kids were competing to create a turbine that would generate the most energy as a part of a challenge for the Duke Energy Academy at Purdue. The annual academy, now in its fifth year, brings in U.S. high school students to learn about renewable energy with hopes they'll be inspired to pursue careers in science, technology, engineering and mathematics fields and solve energy challenges. "We want these students to be the leaders of tomorrow," said Pankaj Sharma, managing director of the Purdue Energy Center and Global Sustainability Institute. The academy lasts throughout the week and is hosting 52 students and 27 teachers from mainly Indiana schools, though about 20 percent come from outside states, said Tolu Omotoso, a civil engineering graduate student and coordinator for the academy.Read Full Story
