New blade was designed by combining the advantage of sweepback and characteristic of flight trajectory. Mass and rotational inertia of turbine were calculated before using UDF and SDOF to build up the condition of fluid-driven simulation and observing the behavior of VAWT with airfoil NACA0012-800, LJY-800 and NACA23012-800. Results showed the potential of new designed airfoil and blade with better aerodynamic stability. Fluid-driven simulation gave out further suggestion that VAWT with high lift-drag ratio coefficient and power coefficient should be validated for its feasibility by fluid-driven simulation.
