BIONIC SHARK FIN COMBINED AIRFOIL BLADE OPTIMAL DESIGN AND NUMERICAL SIMULATION OF HORIZONTAL AXIS TIDAL CURRENT TURBINE
Краткое описание
NACA airfoils are mostly used currently in turbine blades mainly in the aviation field, causing the low efficiency of the turbine. To improve the efficiency, in this paper, the shark caudal fin airfoils with good hydrodynamic performance were selected from the perspective of bionics. According to the characteristics of the lower edge of the shark caudal fin and the radius of curvature of the upper edge of NACA airfoil, a new airfoil was designed that combined the lower edge of shark caudal fin and the upper edge of NACA airfoil and, on this basis, a composite airfoil blade and a turbine model were designed. The high efficiency of the turbine was verified by numerical simulation. The design method is verified to be more suitable for the working environment, and provides a new method for the design of the horizontal axis turbine blade.
