Wind energy plays a significant role as a sustainable and renewable energy source. This paper deals with ANSYS to set up computational fluid dynamics (CFD) and structural analysis and then apply for use them to wind turbine (WT) blades. The present paper selected General Electric's (GE) horizontal axis wind turbine (HAWT) for 1.5 MW of renewable energy and focused on using the ANSYS package to calculate the tip velocity, pressure, power coefficient, deflection, flap-wise, and edge-wise deformation values. The simulation analysis considered three independent variables: wind speeds of (7, 10, 12, 15, and 20 m/s), blade position of (90, 180, 270, and 360⁰ ), and Five composite materials of (Carbon-Epoxy, E-Glass, S-Glass, Kevlar, and Technora). The shear stress transport (SST) turbulence was employed. The results show a good agreement between the tip velocity, power coefficient values, and the numerical simulation. The Epoxy E-Glass material exhibits the maximum blade deflection of 1.6363 m, while the Kevlar material has the minimum deflection of 0.41277 m. At a 90 o angle, the Epoxy E-Glass material shows a maximum blade deflection of 1.4918 m, whereas the Kevlar material has a minimum deflection of 0.37381 m at a 270 o angle. These findings highlight the importance of considering wind conditions and their effects on blade performance and structural integrity in wind turbine design and operation.

Abstract. Given that wind turbine blades are large structures, the use of low-cost composite manufacturing processes and materials has been necessary for the industry to be cost competitive. Since these manufacturing methods can lead to the inclusion of unwanted defects, potentially reducing blade life, the Blade Reliability Collaborative tasked the Montana State University Composites Group with assessing the effects of these defects. Utilizing the results of characterization and mechanical testing studies, probabilistic models were developed to assess the reliability of a wind blade with known defects. As such, defects were found to be best assessed as design parameters in a parametric probabilistic analysis allowing for establishment of a consistent framework to validate categorization and analysis. Monte Carlo simulations were found to adequately describe the probability of failure of composite blades with included defects. By treating defects as random variables, the approaches utilized indicate the level of conservation used in blade design may be reduced when considering fatigue. In turn, safety factors may be reduced as some of the uncertainty surrounding blade failure is reduced when analyzed with application specific data. Overall, the results indicate that characterization of defects and reduction of design uncertainty is possible for wind turbine blades.

This report provides basic documentation of information used to create a CX-100 finite element model using NuMAD. The model is intended for use as a structural model. Use of this model for aerodynamic analyses is to be performed with caution. The CX-100 blade was designed to demonstrate the efficient use of carbon fiber in the spar cap of a wind turbine blade. Refer to the References at the end of this report for full and in-depth information on the CX-100 blade project. 4 ACKNOWLEDGMENTS
