Wind Tunnel Testing And Numerical Simulation On Aerodynamic Performance Of A Three Bladed Savonius Wind Turbine, Khandakar Niaz Morshed, Mosfequr Rahman, Gustavo Molina, Mahbub Ahmed

Department of Mechanical Engineering Faculty Publications

The purpose of this research work is to investigate experimentally and computationally the feasibility of improving the performance of the vertical-axis Savonius wind turbine. The authors first performed a series of wind tunnel investigations on semi-cylindrical three-bladed Savonius rotor scale models with different overlap ratios and without overlap. These experiments were conducted in front of a low-speed subsonic wind tunnel at different Reynolds numbers. Pressures around the concave and convex surfaces of each blade, as well as the static torque for the rotor models, were measured. Using these experimental data, the authors calculated aerodynamic characteristics such as drag coefficients, static …
