In recent years, there has been an increase in the number of research papers on plasma and its use in flow control. The main objective of this study is to improve the performance of the airfoil by shifting the stall angle. In addition, optimization of the plasma actuator position and configuration is to be studied to identify the optimum configuration for maximum stall angle shift. These flow ... [Show full abstract] control study is performed for a NACA0015 airfoil. The experiments were conducted in a wind tunnel at Reynolds number of 4.8×104. The plasma actuators are mounted on various positions (x/C) starting from the leading edge to trailing edge of the airfoil. The electrical parameters used for the plasma generating device are set to constant values of 7 kVpp applied voltage and 3.5 kHz excitation frequency. The experimental results on force measurement is presented to illustrate the effect of the generated plasma on shift of the stall angle . The results of the study suggest that the energy efficiency of airborne systems can be improved with the use of plasma actuators due to its increasing lift and decreasing drag coefficient effects. This result becomes a vital finding considering that same flight can be achieved with less fuel and less amount of environmental pollution for the same distance of journey.
