In this paper, we studied two different rotor blade designs of 1kw of Horizontal axis wind turbine (Hawt) using commercial CFD software Ansys Fluent. The baseline design is developed using a genetic algorithm by considering the starting time and power coefficient as design parameters. The improved design is developed through an iterative approach using open-source software QBlade. Detailed aerodynamic characteristics of both blade designs are investigated and compared with CFD results that shows the maximum power coefficient of the improved design is 11% more than the baseline design. The CFD results demonstrate that aerodynamic performance of improved blade not only increased in design point but also better performs in off-design conditions. A Grid independence study is conducted to check variations in results, and the y-plus value is also investigated along entire blade surface to ensure that mesh is fine enough for selected turbulence model.
