Wind power is one of the most important sources of renewable energy. Wind-turbines extract kinetic energy from the wind. Currently much research has concentrated on improving the aerodynamic performance of wind turbine blade through wind tunnel testing and theoretical studies. These efforts are much time consuming and need expensive laboratory resources. However, wind turbine simulation through Computational Fluid Dynamics (CFD) software offers inexpensive solutions to aerodynamic blade analysis problem. In this study an optimal wind turbine blade is taken for study purpose. The wind turbine GE 1.5 XLE turbine which consist a hybrid blade which is made of S818 S825 and S826 at root mid and tip respectively is used to simulate in low wind speed environment. For this FSI (Fluid Solid Interaction) method can be used which works on governing equations of continuity and Navier-Stroke’s equation. In this work the CFD simulation as well as FEA simulation will be carried out one after another which gives us the fundamental results related wind turbine operation in desired environmental condition. CFD model is simulated using ANSYS-FLUENT module. As wind condition favours low wind speed regime in our study hence we can perform initial analytical study by using Blade Element Moment theory (BEM).
