Fluid-Structure Coupling Analysis of Small Vertical Axis Wind Turbine Blade
A vertical axis wind turbine blade with rotation diameter of 2m is selected as the research object.The research object is a 1000W vertical axis wind turbine blade with NACA0021airfoil.The numerical simulation and experiment are used to verify each other.Analysis vertical axis wind turbine blade with experimental displacement test and the fluid structure coupling analysis of the blade is carried out by using ANSYS Workbench.The system coupler is called to realize the mutual transmission of data,and the bidirectional coupling calculation of the blade is completed.The displacement,stress and strain of wind turbine blade under different working conditions are studied.The results show that the wind load makes the blade deformation and there is a large dis-placement along the blade spanwise.With the increase of wind speed,the blade displacement increases significantly.The pressure in the upstream direction is greater than that in the downstream direction and the displacement and deformation curve fluctuates up and down along the spanwise direction.
