Fluid-Structure Analysis of Airfoils on the Small Wind Turbine

Abstract:

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 . The design and calculation on thickness of airfoils were studied in order to raise its life and reduce weight. In the premise of strength, the lighter, the better. This paper studied the aerodynamic performance of the airfoil under the Low-Reynolds and analyzed fluid-structure interaction effect under three different attack angles. The numerical simulation approach addresses unsteady Reynolds-averaged N-Stokes solutions and covers transition prediction for unsteady mean flows. The computational result and the analysis show that the fluid-structure interaction is an important issue to consider while designing the wind turbine blade. The results may provide technical reference for the further wind turbine design.
