This paper presents a detailed analysis of Archimedes Screw Turbines (ASTs) within the renewable energy sector, particularly in hydropower applications. Using bibliometric analytic methods, including bibliographic coupling, we systematically explore the evolving knowledge landscape of ASTs. This approach allows us to map and identify emerging and current research themes, emphasizing key areas for future study and development. Our findings reveal a significant focus on design characteristics and their impact on optimizing AST performance. Notably, recent research has increasingly concentrated on refining AST configurations to enhance power output and overall efficiency. This trend reflects a broader effort to consider performance-influencing factors and integrate innovative solutions into AST design practices. By highlighting these critical areas, our study contributes to the ongoing advancement of AST technology, offering insights that will guide future research and design improvements in this field.
