In this report, numerical analyses of performances of prototype Mg-alloy micro vertical axis wind turbine (VAWT) were conducted. It has three wings with usual NACA0018 wing section. Typical Reynolds number based on the wind speed and the wing chord length were set around 3.3×104 with consideration of use as a portable-type micro VAWT system for engineering educations. In such low Reynolds number cases, somewhat different way of design would be required because of flow separation and reattachment, short bubbles etc. We also examined a torque variation generated from the wings using 3-D unsteady CFD analysis and compared the results and flow patterns for higher performance.
