The blade profile of the Darrieus Vertical Axis Wind Turbine is very influential against the drag force and lift force, and power output. This research aimed to determine the maximum turbine power performance of Darrieus VAWT using the blade profile NACA 2412 airfoil with a camber radius and thickness of 50%. The 2D profile of the turbine blade was created based on web applications airfoiltools.com with specific chord lengths, radius 137.5 mm, and 50% thickness, then converted to AutoCAD. At the same time, 3D Geometry was created by using Solidworks software. The magnitude of drag coefficient, lift coefficient, drag force, and torque was analyzed using CFD Flow Simulation and experiment. Drag force was also calculated analytically and validated with software and experiment. From the simulation and experiment results showed that the torque and power output were obtained at 30°, 120°, 210°, and 300° azimuth angle with the maximum Cp of 0.46.
