Study of Parameter Design and Aerodynamics on Bending Characteristics of VAWT Airfoil

This paper studies the influence of airfoil camber (f) on the aerodynamics of H-type vertical axis wind turbines. v=4,8,12m/s is selected as the design condition, and the NACA0015 airfoil (f=0%) is used as the prototype for the parametric design. A total of 6 different airfoils with camber from 0% to 5% are desiged, and a two-dimensional CFD simulation model is established through ANSYS software. Taking wind energy utilization rate Cp and high-efficiency wind energy operating area Δλ as research objects, the aerodynamic laws of VAWT and the changes in torque, pressure, and speed of airfoil surfaces under different azimuth angles are studied. The study finds that the camber has a great influence on the aerodynamic performance of the vertical axis wind turbine, and the airfoil with a smaller camber of [0%,2%] has better aerodynamic performance.
