Darrieus type Vertical Axis Wind Turbine (VAWT) is attracting many researches for its inherent advantages and its diversified applications. However, a disadvantage is when the rotor is stationary; no net rotational force arises, even at high wind speed. The objective of this study is to show the effect of camper airfoil on self starting of VAWT at low Reynolds. A moving mesh technique was used to investigate two-dimensional unsteady flow around a vertical axis wind turbine. The geometry of the turbine blade was NACA2415 camber airfoil. The turbine model was created in Gambit modeling software and then read into fluent software for fluid flow analysis. Simulations of the model were then conducted for different tip speed ratios. The simulation result shows that camber airfoils have the potential to self start for the modeled airfoil with reduced coefficient of power. |
