Abstract
The development of wind turbine attracts more attention as a renewable energy. Layer Laminated Bamboo Composite (LLBC) is a prospective material for rotor blades of low speed wind turbine. Airfoil S834 is commonly used for blade of low speed wind turbine. But there are other airfoils that can be considered, namely S835, S809 and NACA 0012. This research addresses which airfoil shows the best performance for low speed wind turbine. The blade material for wind turbine is LLBC (Laminated Layer Bamboo Composite) which is combination of Gombong Bamboo and Standard Resin. The blade has incidence angle 16° and twist angle 16°, respectively. The four blade configurations were compared with the standard blade using ANSYS CFX simulation. The simulation was carried out with 7,9 million elements, frozen rotor as model for interface between static mesh and rotated mesh. The simulations resulted that S834 airfoil showed the best performance as indicated by the highest power generated.
