The Investigation of the Small Bionic Wind Turbine Based on the Seagull Airfoil

Abstract:

With the requirement of renewable energy and sustainable development, green energy resources are more and more fashionable and focused. Among of them, small wind turbine is popular and with many customers because it has an unique feature. For the blades of the small wind turbine working under the conditions of Low-Reynolds, the air viscosity has relatively greater influence on its aerodynamic performance. This is one of the greatest difficulties to design a small wind turbine. This paper studied the aerodynamic performance of the airfoil under the Low-Reynolds and designed a blade based on the airfoil of the seagull. The CFD computational result and the analysis show that the airfoil of the seagull is suitable for the special work circumstances of the small wind turbine, and it can be used for the further design of the blades. The results may provide technical reference for the wind turbine deign.
