A Computational Fluid Dynamic Simulation of Three-Dimensions of a Small Horizontal Axis Wind Turbine Blade

This research employs Computational Fluid Dynamics (CFD) simulations to investigate the aerodynamic characteristics of a wind turbine blade. Focusing on critical parameters such as velocity, pressure, and streamlines, the study provides a thorough analysis of fluid dynamics during the interaction between the rotating blade and wind. Specific attention is given to three distinct segments along the blade span, revealing detailed insights into airflow patterns and pressure distributions. The examination of velocity vectors demonstrates the circular trajectory at the blade tip, a consequence of the rotational movement interacting with the wind. Streamlines, depicting fluid particle paths, offer valuable information on turbulence and vortex formation. The study emphasizes the significance of pressure in inducing blade deflection, crucial for operational dynamics. Detailed analysis of pressure distribution along the blade span underscores the importance of pressure variations. Contours reveal the stagnation point at the leading edge and the lift generated on the airfoil. The research provides a foundation for optimizing wind turbine blade designs, contributing to enhanced efficiency and performance in the quest for sustainable energy solutions.
