Abstract:

A swept blade was designed based on NREL phase VI test blade. The CFD simulation results show significant radial flow on the aft-swept blade. The flow around aft-swept section turns to the rotor center around leading edge and turns to blade tip around trailing edge arresting. The analyses indicate that blade aft-sweeping transforms the flow condition, and it turns streamline around leading edge to rotor center and turns streamline around trailing edge to blade tip with coaction of centrifugal force and Coriolis force.

Key words: wind turbine, aft-swept blade, aerodynamics, CFD
