| Abstract: | For studying the influence of airfoils on the start-up characteristics of vertical axis wind turbines,a asymmetric airfoil named S809 and a symmetrical airfoil named NACA0018 were chosen as blades.Firstly,the static torque was obtained by numerical simulation,and the azimuth angle with obvious difference was obtained,and the vorticity and vector diagram were obtained.visualization experiment was used to verify simulation results.Combining with them,the flow field were analyzed.The results show that NACA0018 airfoil has better start-up performance than obverse-installed S809 airfoil.The vortex of blade wake flow makes the flow field unstable and causes energy loss.The wake flow of both airfoils generates vortices with varying degrees,making the flow be complex.Compared with NACA0018 airfoil,the shear flow at the back of the obverse-installed S809 airfoil is stronger,and the vortices are closer,thus influence is more significant. |
