Ahmed S. Saad,Ahmed S. Saad,Ibrahim I. El-Sharkawy,Ibrahim I. El-Sharkawy,Shinichi Ookawara,Shinichi Ookawara,Mahmoud Ahmed,Mahmoud Ahmed +7 more
TL;DR: In this paper, the effects of several design parameters including twist angle, overlap ratio, and endplates size ratio, along with the wind velocity on the performance of the Savonius wind turbine are investigated.
Journal ArticleDOI
Investigating the performance of a twisted modified Savonius rotor
TL;DR: In this paper, the performance of a twisted modified Savonius rotor at various twisting angles was investigated in front of a free air jet and the computations were performed using the three-dimensional incompressible unsteady Reynolds-Average Navier-Stokes (RANS) equations along with the RNG k-e turbulence model.

TL;DR: In this paper, a new configuration using twisted blades in multi-stage Savonius rotors is developed to enhance the performance of vertical axis wind turbines, and a comprehensive three-dimensional unsteady incompressible turbulent flow model using Reynolds-Averaged Navier-Stokes equations along with k-ω shear-stress transport turbulence model is developed.
Journal ArticleDOI
Experimental and Theoretical Studies for Improving the Performance of a Modified Shape Savonius Wind Turbine
TL;DR: In this article, the performance of a 45-degrees twisted Savonius rotor with a modified profile, at various overlap ratios (δ), aspect ratios (AR), and wind velocity (V), was evaluated on a free air jet test rig.
Journal ArticleDOI
Performance Analysis of a Helical Savonius Wind Turbine with Modified Rotor
TL;DR: In this paper, the authors investigated numerically the performance of a helical Savonius wind rotor with a twist angle of 45°, where the twist is performed on a modified profile of the rotor blade.
