N2 - This study aimed to investigate how the performance of the Savonius wind turbine, characterized by blade diameter (D) of 165.2 mm, end plate diameter (Do) of 320 mm, and shaft diameter (b) of 19 mm, is influenced by the introduction of D-type cylinders as disturbances. These cylinders were added with various cutting angles (θs) of 0°, 53°, and 65°. The research was conducted using a 2D simulation using FLUENT 2021 R2, operated at a wind speed of 7 m/s or equivalent to the Reynolds number (Re) = 1.5 × 105. A circular cylinder is placed ahead of the turbine at a distance where S/D = 1.25 and y/D = 0. The outcomes indicated that incorporating a cylinder with specific cutting angles can lead to an augmentation in the maximum power coefficient value of the turbine. The maximum power coefficient value of the turbine (Cpmax) with D-53° type disturbance is 0.18737at tip speed ratio (λ) = 0.6. This value is 1.025 times greater than that of a conventional turbine. But unfortunately, the placement of the D-0 type and D-65° type cylinder in front of the turbine makes the maximum power coefficient of the turbine only 0.17363 and 0.16259, which is 5 and 11.06% lower than the conventional turbine one.
