In wind turbine blade, most of the losses occurs due to aerodynamic losses in the post stall operating condition. Adoption of the blade leading edge tubercles improves the post stall aerodynamic performance. Nevertheless the geometric parameters of the protuberance play a vital role in influencing the aerodynamic performance, it is possible that shape of the protuberance may also have aerodynamic significance. In this paper different types of tubercle shapes are adopted on the blade leading edge to study the improvement in the aerodynamic performance. Each of the shape is studied for different AOA operating at Reynolds number of 3 × 105. The results revealed that the shape of the tubercles also influence the flow which affects the performances. |
