Abstract
In this study, the performance of different wind turbines is compared using Qblade software. Typically wind turbines are categorized as Horizontal Axis Wind Turbine (HAWT), and Vertical axis wind turbine (VAWT) which in this paper Darrieus type as a VAWT is discussed with HAWT. The airfoil selected for this study is NACA 0012, and from simulations, it can be seen in which wind speed range, each type has higher efficiency. Then, the parameters involved in their performance is discussed, and suggestions are made on how to modify them to have a higher output power. Qblade contains the XFOIL airfoil analysis functionalities which make a software a single tool which comprises all functionality needed for the design and simulation of vertical and horizontal axis wind turbines. The benefits of the proper airfoil design optimal are increasing the efficiency of wind turbines and maximization of the power produced.
