2.1. Wind turbine rotor design
The Savonius blades were modeled on a variation of classic Savonius rotor. The VAWT used for this study is a
semicircle shaped blade made from fiber glass material. The rotor radius is 150 mm and the height of each blade is
75 mm. Two rotors: one with 16 blades and another with 8 blades were constructed. The schematic of the rotors are
shown in Fig. 1(a) and Fig. 1(b) shows a 3D model of the assembly for 16-bladed turbine rotor
