- As a renewable energy, wind energy becomes one of the promising energy technologies. Most wind turbine technologies are designed at high speeds which are not effectively operated in areas with low wind speeds. Therefore, an effective technology to enhance the possible use of wind energy at low wind speeds is needed. The concept of Diffuser Augmented Wind Turbine (DAWT) has been used recently to improve the use of wind turbine in a low wind speed area by manipulating the wind speed. The pressure difference between inside and outside of the diffuser is generated which might enhance the wind velocity; hence, the power is increased. In this paper, simulation using ANSYS was conducted to investigate the performance of Horizontal Axis Wind Turbine (HAWT) in low wind speed area applying DAWT technology by modifying the angle of the diffuser. The variation of the diffuser angle was in the range 4- 16o and the diffuser length to diameter (L/D) is 1.25D. The simulation results showed a good agreement with the reference literature which obtained the increased power around 1.2-1.7 times higher than the non-diffuser wind turbine.
