The S-rotor wind turbine operates based on drag, resulting in lower power coefficients. Furthermore, a multitude of geometric and aerodynamic factors have been meticulously crafted to enhance the overall efficiency. The augmentation technique decreased the adverse drag force produced by the S-rotor. Therefore, in this investigation, the elliptical bladed profile has been selected for simulation in conjunction with the curtain plate preceding the rotor. The simulation has been conducted in Ansys fluent platform. So far the comparison has been performed for power vs RPM for S-rotor blades and elliptical rotor blades. For elliptical rotor blades, the peak power magnitude of 10 W and average power of 7 W are achieved. From conventional S-rotor blades, the peak power magnitude of 8 W and average power of 4 W are obtained. It has been determined through contour plot analysis that the aerodynamic performance of an elliptical bladed profile with curtain plates surpasses that of an elliptical profile without curtains.
