Efficiency Analysis of 3D Wind Turbine Blade Performance Based on Blunt Trailing Edge Airfoil Blade

doi:10.3901/JME.2023.06.123

Abstract

Abstract: With the development of large-scale wind turbine, blunt trailing edge airfoil was applied to the design of wind turbine blade to effectively improve the performance of wind turbine blade. Using NACA639XX series airfoils as reference airfoils, the airfoils were parameterized by hicks-Henne type function and blunt trailing edge function, and the laminar flow blunt trailing edge airfoils family (USST-XXX) is optimized by multi-island genetic algorithm. The USST-211 airfoil with 21% relative thickness and the NACA63921 laminar flow airfoil replace the S809 airfoil with NREL Phase VI blade section in this airfoil family, and two kinds of 3D wind turbine blades are modeled. The flow field of these two blades under different wind speeds is analyzed by numerical simulation. Compared with NREL Phase VI wind turbine blade aerodynamic performance. The numerical simulation results show that the wind energy utilization coefficient of the new blade is higher than that of the other two blades near the rated wind speed. The results show that the optimized laminar blunt trailing edge airfoil family can effectively improve the aerodynamic performance of wind turbines, and has a good application prospect in blade design of large horizontal axis wind turbines.
