“…The computational domain of the model in this study includes the entire blade and a portion of the surrounding air. The blade is discrete into many small elements, and the fluid flow over each element is analyzed using ANSYS Fluent software [10,27,28]. The model's boundary conditions are set to simulate real-world conditions, including the incoming wind velocity, the outlet's pressure, and the blade's rotational motion.…”

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.

“…They found out the power coefficient decreased in the case of extremely low turbulence intensity. Hren [9] performed a numerical analysis of a wind turbine blade with different software using Ansys CFX and SolidWorks. He found that plug-in software is still inadequate for nontrivial problems.…”

The present work focuses on the comparison of the capabilities of Blade Element Momentum Theory, with and without the high induction factor value model and Computational Fluid Dynamics modelling in relation to experimental measurements of the power coefficient for a model-sized horizontal axial wind turbine. Initially, an analytical investigation was performed to obtain the power coefficient curve. Furthermore, three-dimensional numerical simulations were performed, where a lot of effort was devoted to the preparation of a low y+ structured mesh. Analytical and numerical results of the power coefficient were compared with experimental results, which were obtained with our own conducted experiments in the wind tunnel. The most significant conclusions are that the classic BEM method deviates from measured data in the entire range of tip speed ratios, the BEM method with Spera correction predicts a significantly better agreement with experimental measurements compared to the classic BEM method, especially the part where the power coefficient decreases and finally that CFD computations can accurately predict the performance of wind turbines and compute the flow around an aerofoil of the blade.

“…However, simulating wind turbine through Computational Fluid Dynamics (CFD) software offers inexpensive solutions for efficiently analysing it. The deformation of the blades and the resulting stresses produced in the turbine blades are the most important parameter predicting the strength of the blades to withstand harsh wind conditions and the aerodynamic performance of the turbines [13,14]. The main aim of the current study was to compare the strength and analyse the deformation behaviour of wind Horizontal Axis Wind Turbine blades made of composite and aluminium alloy.…”

This study compares the strength and deformation in blades of a horizontal axis wind turbine made of composite and aluminium alloy. A 3D geometric model was generated and imported into a Finite Element code for the purpose of analysis. The Computational Fluid Dynamic (CFD) analysis was coupled with structural analysis using one-way fluid structure interaction. The deformation and stresses produced in the two types of blades (aluminium alloy and composite) were analysed and compared. The tip deflection and stress on the blades were related to the wind speed and Yaw angles. The obtained results are compared and discussed in the context of similar studies available in the published literature.
