The Blade Design of a Bionic Shark Fin Airfoil for a Horizontal Axis Tidal Current Turbine

The horizontal axis tidal turbine is a typical apparatus to capture the energy in the ocean, but most traditional design methods of a turbine blade have led to the inefficiency of turbines. Therefore, to improve turbine efficiency, a design methodology of a horizontal axis tidal turbine blade based on bionics research is presented in this work. First, the point cloud of fin samples was scanned and processed. The three-dimensional digital models …
