Abstract: In the current age of global energy crisis, the production of energy through alternate energy resources has gained a significant attention. Wind as a source of energy is a very attractive due to the fact that fuel is free of cost. This research is about the aerodynamic design of a VAWT (Vertical Axis Wind Turbines) blade using the analytical and CFD techniques. The blade design parameters and dimensions are taken aiming the required power output, and CAD models are developed to evaluate the aerodynamic forces, like lift and drag, over the surface of the blade. These forces which are very helpful for the evaluation of the structural integrity of the VAWT blade are then found to be in a close agreement with CFD results which are simulated using commercial software - ANSYS 19.0. The static CFD model is developed at a selected pitch angle during a complete 360° where the aerodynamic forces evaluated. VAWT blades has a dominant role in the generation of the aerodynamic forces and the power generation of the turbine. However, there is a significant uncertainty in determining the blade AOAs during operation due to very complex flow structures, and this limits the turbine design optimization.
