Evaluation of Savonius rotor performance: Static and dynamic studies
MH Nasef, WA El-Askary, AA Abdel-Hamid… - Journal of Wind …, 2013 - Elsevier
An aerodynamic performance of stationary and rotating Savonius rotor for various overlap
ratios is numerically analyzed using four turbulence models. The simulation is compared
with the present and published experimental results to determine the suitable turbulence
model. The computations are statically and dynamically performed at different rotor angles
ranging from 0° to 180°. Five rotors, having two semicircular blades, but with different
overlap ratios; reading 0, 0.15, 0.2, 0.3 and 0.5 are considered. The results indicate that the …
