The rapid growth in fossil energy demand has led to various environmental impacts, while energy access in remote, frontier, and underdeveloped (3T) regions remains limited. The utilization of renewable energy, particularly wind energy, offers a potential solution. However, since wind speeds in these regions are generally low, it is necessary to design low-speed wind turbines with appropriate blade materials to ensure optimal operation.
In this study, the turbine blade was designed using QBlade with a tip speed ratio (TSR) of 6 and tested under wind speed variations of 3.8, 4.5, 5.2, 6.0, and 7.3 m/s, based on wind characteristic data from Pantai Baru, Yogyakarta. Performance analysis was carried out through numerical simulations using ANSYS with the Fluid-Structure Interaction (FSI) approach to evaluate both aerodynamic performance and structural responses of different blade materials.
The results indicate differences in power output, where QBlade produced values ranging from 36.73 to 431.79 W, while CFD ANSYS generated 21.86 to 251.22 W. Despite the differences, both showed consistent upward trends with increasing wind speed. FSI analysis revealed that epoxy carbon fiber UD 395 GPa provided the most optimal performance with minimum deformation and the highest power output, whereas aluminum alloy exhibited significant deformation and epoxy S-glass demonstrated moderate performance. Therefore, epoxy carbon fiber UD 395 GPa is recommended as the most suitable material for low-speed wind turbine blades.
