Experimental Study on Combined Savonius and H-Rotor Darrieus Vertical Axis Wind Turbine with NACA Airfoil as its Blade

摘要

The objective of this research is to conduct an experimental study of the performance of the vertical wind turbine (VAWT) combination Savonius and H-rotor Darrieus. Three models will be tested: a combination of NACA 4515-0012, a combination of NACA 6515-0015, and a combination of NACA 8515-0018 herein after refer as VAWT A, VAWT B, and VAWT C. Testing conducted using subsonic wind tunnel with various wind speed between 3 m/s to 15 m/s. Experimental result will be compared and analyzed. The results of this study showed that VAWT B had the best performance, the highest TSR is 0.4188 at wind speeds of 15 m/s. While VAWT A and C shows better self-starting, capabilities compare to VAWT B.
