The savonius rotor blades (the model) was designed and fabricated. The model was tested in the wind tunnel for
various air flow speed conditions.
The material choice to fabricate such models for two and three savonius wind turbine depends mainly on many criterions.
Aluminum is the best choice due to its light weight, corrosion resistance, rigidity, recyclable materials, easy to construct and
low cost [ref. 8]
.
The dimensions of these rotors were selected to have an aspect ratio (Aa = H / D = 1), thus the blades (scoops) were made of
semi-cylindrical scoops of diameter (d = 100 mm), height of (H = 200 mm) and thickness of (0.079 mm).
These blades were assembled and mounted on two Aluminium disc sheets (End plates) of diameter (Do = 210 mm) and
thickness of (1.59 mm) to obtain a better performance (figure 4). Both the semi- cylindrical blades and the two end plates
