  • Abstract
    The study was a simulation of the organization of the axial wind turbines, the resistance type and three-piece lift-type structure, resistance type is semi-circular arc type, lift type of blade were NACA0018 airfoil and NACA4412, the inflow and rotational flow interactions. CFD computational fluid dynamics methods using finite volume method to solve Navier-Stokes equations to SIMPLE algorithms for incompressible flow, coupled with second-order upwind and dependency by testing the grid with the grid and the analytical characteristics of the turbulent flow pattern transition, And the other with sliding mesh method, and the additional number of dynamic flow rate of angular momentum, CFD simulation, the resistance type and NACA0018 and NACA4412 torque output, the more complex the fan if installed NACA0018 and NACA4412 additional vertical axis wind turbine will also improve the two Species of the wing part of the export value of the reverse. Only the resistance-type than the original state of the torque output value can be 3.6 times higher.
