Abstract
The use of small wind turbines to generate electricity is becoming increasingly common around the world. This energy source is still understudied when compared to studies on medium and large wind turbines. The model presented here has three fixed straight blades; in the future, this model will have motorized blades. In addition, lift and drag coefficients for the applied airfoils were calculated using the same numerical model as for the vertical-axis wind turbine (VAWT) using the same numerical model. When using a Reynolds number of 2.9 million, the obtained values of lift and drag force coefficients match with XFOIL’s and the experiment’s predictions throughout a wide range of angles of attack. As a result, this impeller is attractive for further investigation due to its maximum rotor power coefficient of 0.5. According to research, if this rotor is to be used with fixed blades, the NACA 4418 airfoil should be used instead of the original NACA 0015 and NACA 0018. Angle of increment 00, 50, 100, 150 and velocity variants input from 5, 5.5, 6, 6.5, 7, 7.5, 8 m/s. As a result, the pressure distributions in all input parameters have been observed. ANSYS Fluent was used to analyse all airfoils’ aerodynamic performance.
