| description | ABSTRACT As the demand for power increases, installing small‐scale wind turbines can be an alternative solution. However, the main challenge for their implementation is the aerodynamic noise. With a view to minimizing noise, this study focuses on the performance investigation of a small‐scale horizontal‐axis wind turbine with NACA 4412 blades inspired by humpback whale flippers (trailing‐edge tubercles and inward dimples). Wind turbines with conventional NACA 4412 blades and modified biomimetic NACA 4412 blades were tested in six angles of attack (AOAs) between wind speeds of 4 and 11 m/s. The cut in speed was less for the modified bladed wind turbine and delivered higher rotational speed than the conventional one. The wind turbine equipped with the modified blade produced a power output of 14.98 W at a wind speed of 8.8 m/s, surpassing the 13.72 W, generated by the conventional bladed turbine. At 30° AOA, the power coefficient of the modified bladed turbine was 56.43% higher, and the sound pressure level was 2.99% lower. Hence, the redesigned biomimetic NACA 4412 bladed design improves wind turbine efficiency and results in noise reduction, potentially enabling more sustainable wind energy options. |
