Title

WIND TUNNEL TESTING AND NUMERICAL SIMULATION ON AERODYNAMIC PERFORMANCE OF A THREE-BLADED SAVONIUS WIND TURBINE

Pages

  1-14

Abstract

 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 TORQUE COEFFICIENTs, and POWER COEFFICIENTs. The authors then performed computational fluid dynamics (CFD) simulations using the commercial CFD software FLUENT and GAMBIT to analyze the static rotor aerodynamics of those models. The experimental and computational results were then compared for verification. Three different models with different OVERLAP RATIOs were designed and fabricated for the current study to find the effect of OVERLAP RATIOs. The results from the experimental part of the research show a significant effect of OVERLAP RATIO and Reynolds number on the improvement of AERODYNAMIC PERFORMANCE of the SAVONIUS WIND TURBINE. At higher Reynolds number, the turbine model without OVERLAP RATIO gives better aerodynamic coefficients, and at lower Reynolds number, the model with moderate OVERLAP RATIO gives better results.
