Performance prediction of NREL (National Renewable Energy Laboratory) Phase VI blade adopting blunt trailing edge airfoil

▸ The blades adopting flatback airfoils are designed and used to compare with the original blades. ▸ 1% Blunt blade, 5% Blunt blade, and 10% Blunt blade geometry are redesigned. ▸ The aerodynamic advantages of the redesigned blades are investigated. ▸ We observe the blunt effect and each blade's characteristics.
