ABSTRACT
Numerical results are presented for aerodynamic unsteady and steady airfoil characteristics
of the NACA 0018 airfoil of a two-dimensional vertical-axis wind turbine. A geometrical
model of the Darrieus-type wind turbine and the rotor operating parameters used for numerical
simulation are taken from the literature. Airfoil characteristics are investigated using
the same mesh distribution around the airfoil edges and two turbulence models: the RNG
k-" and the SST Transition. Computed results for the SST Transition model are in good
agreement with the experiment, especially for static airfoil characteristics.
