The analysis of the aerodynamics for the vane type vertical axis wind turbine (VVAWT) with different blades and vanes position is carried out using computational fluid dynamics (CFD). In the present design, there are three blades each having three movable vanes. The power generated depends on the drag force generated by the individual blades and interactions be-tween them in a rotating configuration. For numerical investi-gation, commercially available computational fluid dynamic CFD software GAMBIT and FLUENT are used. In this numerical analysis the Shear Stress Transport (SST) k-ω turbulence model is used which is better than the other turbulence models available as suggested by some researchers. The computed results show good agreement with published experimental results.
