Comprehensive Analysis of Blade Design Parameters and its Influence on Performance of Micro Wind Turbine

Micro-wind turbines are crucial elements of distributed energy systems, especially in areas with moderate wind velocities. Their efficacy is significantly influenced by the aerodynamic and structural configuration of the blades. This paper presents a thorough analysis of the principal blade design parameters namely chord length, twist angle, airfoil selection, blade count, and solidity and their impact on turbine performance. Analytical equations are derived using the Blade Element Momentum (BEM) theory to model the influence of these parameters on performance metrics such as the power coefficient, starting torque, and cut-in speed. Computational Fluid Dynamics (CFD) simulations augment the theoretical analysis. This study enhances the design optimization of micro-wind turbines, providing actionable insights for future advancements. Major Findings: The results indicate that optimizing chord length and twist angle markedly improve energy capture and startup performance, while suitable airfoil selection guarantees operational efficiency at low Reynolds numbers.
