The quest for efficient and environmentally sustainable energy sources has intensified the exploration of wind power, with vertical axis wind turbines (VAWTs) emerging as promising alternatives to traditional horizontal axis designs. Among VAWTs, the Savonius turbine, renowned for its simplicity and reliability, stands out as a viable option for various applications in urban and rural environment. However, optimizing Savonius turbines to enhance performance while minimizing operational drawbacks remains a significant research focus. This paper presents a thorough investigation of influence of end plates on the performance, stability, noise emissions, and vibrational characteristics of Savonius VAWTs. Employing a computational simulation on ANSYS R12023, the study provides detailed insights into the aerodynamic behaviors and operational attributes of turbines with and without end plates. Output results reveal distinct performance disparities between the two turbine configurations, with Savonius VAWTs equipped with end plates demonstrating notably higher coefficients of power and torque. The results suggests that an increase of up to 86% in power coefficient (Cp) and 85% in torque compared to turbines without end plates. The findings of this study underscore the multifaceted benefits of integrating end plates into Savonius VAWTs, encompassing performance enhancement, stability improvement, and noise mitigation.
