Wind energy has emerged as a promising renewable energy source, offering sustainable and clean energy. However, maximizing wind turbine efficiency and costeffectiveness remains a critical challenge. This research focuses on the design and parametric analysis of a horizontal-axis wind turbine (HAWT) with a target power output of 100 kW at a wind velocity of 10m/s. The study employs a comprehensive approach that encompasses parametric analysis of various airfoil geometries and angles of attack using Ansys Workbench, and Q-blade coupled with an in-depth evaluation of economic factors. The research commences the investigation of different airfoil profiles, including NACA 2412, S 1020, and K 3311. These airfoils are subjected to a parametric analysis, examining their performance characteristics across a range of angles of attack. The analysis utilizes computational fluid dynamics (CFD) simulations to assess the lift and drag coefficients of each airfoil. In parallel with the airfoil analysis, the economic aspects of the HAWT design are carefully considered. Cost-benefit analysis is employed to evaluate various design parameters, such as blade material selection, and manufacturing processes. In conclusion, the research provides a comprehensive framework for designing a 100 kW HAWT that optimizes power output while maintaining economic viability. The study's findings offer valuable insights for wind energy practitioners and researchers, contributing to the advancement of wind turbine technology and the realization of sustainable energy solutions.
