The effect of the wavy leading edge known as tubercles, as seen on humpback whales, is attained on a tubular model using dielectric barrier discharge plasma actuators. Circular shaped plasma actuator is designed and fabricated to achieve this effect so that when activated it alters the flow field by the formation of bubble-like regions. Properties of circularly shaped plasma actuators are studied experimentally for both steady and duty cycle mode in still air using Particle Image Velocimetry technique to determine the optimum plasma actuator design and operating conditions. These actuators are then placed on a tubular model and tested in the wind tunnel and by use of Particle Image Velocimetry, to examine how the flow field is altered. The formation of the bubble-like region is found, which showed the plasma actuators can be used as plasma leading-edge tubercles. This implies tubercles can be achieved on a wing without changing the shape of the model using circularly shaped plasma actuators. These actuators are then placed on the leading edge of the wing model and aerodynamic properties of the model were measured using balance. The results showed that plasma actuator can be used as tubercles on a conventional shape straight leading edge wing.
