Findings from Center for Drug Evaluation and Research (CDER) Provide New Insights into Mechanical Engineering and Machinery (Aerodynamic Performance Investigations of Savonius Twin-rotor Wind Turbines).

This article discusses a study conducted by the Center for Drug Evaluation and Research (CDER) on the aerodynamic efficiency of a Savonius vertical-axis wind turbine. The study used computational simulations to evaluate the impact of different blade shapes on the turbine's efficiency. The results showed that a rotor with elliptical blades had the highest aerodynamic performance, with an 80% increase in power coefficient compared to the classic semi-circular profile. Additionally, a twin-rotor configuration using elliptical blades further enhanced the power coefficient, reaching 110% compared to a single rotor with semi-circular blades. The research provides valuable insights into improving the efficiency of wind turbines. [Extracted from the article]
