The ultimate aim of this research is optimizing high- performance Horizontal Axis Wind Turbine (HAWT) associated with using Computational fluid dynamics (CFD) to predict the ﬂow behavior over wind turbine blades. Computational prediction of the ﬂow over wind turbines is a challenging numerical problem because of the complicated aerodynamics and large variation in length scales. Phenomena such as; the unsteady flow, vortex shedding of the blade tips, ﬂow separation, complicated blade geometry due to variable twist and chord and changes in angle of attack, and highly turbulent ﬂow over blade sections makes CFD prediction challenging, as well as interesting. The goal is to gain an in depth...
