| Summary: | This study is conducted to investigate the performance of a modified Savonius wind turbine. A 2-dimensional rotor blade model is introduced for computational analysis using ANSYS-Fluent. To make the analysis, Shear-Stress Transport (SST) k-ω turbulence model is used to conduct the analysis. The proposed modified model is compared with a reference model. The coefficient of power (CP), coefficient of torque (CT), and total power (P) for several tip speed ratio (TSR) is evaluated considering single rotation. The proposed model depicted its best performance for all parameters at TSR = 1.1 than the reference conventional model (TSR = 0.7). Furthermore, the proposed model also surpasses the performance of the conventional one at TSR = 0.7. The optimal torque was found 7.02 N-m, which is 62.5% higher than the traditional design.
