DARcorporation engineers were involved with the aerodynamic and structural design of the Wind Energy Corporation Windy II Vertical Axis Wind Turbine (VAWT). Two-Dimensional Computational Fluid Dynamics (CFD) trade studies were conducted to see the effect of number of blades and the profile of the blades. Three-Dimensional CFD cases followed the Two-Dimensional CFD analyses. The performance characteristics were extracted from the Three-Dimensional CFD runs. DARcorporation engineers tested a scaled model of the wind turbine in the wind tunnel at the University of Kansas. The results were post processed and scaled up to the full scale. DARcorporation engineers were also involved with the structural analysis of the wind turbine. A Finite Element model was created and various load cases were analyzed. Layup schedules were determined based on the results from these simulations. Normal modes and frequency response of the wind turbine along with the tower was analyzed using NEi Nastran and Femap.
