Studies and Research on the Trajectory of Streamlines in E.O.S. (Horizontal Kaplan) Turbines

The paper presents a detailed hydromechanical analysis of the flow in horizontal Kaplan turbines, with a focus on the trajectory of the streamlines in the essential areas of the installation. The three-dimensional structure of the flow, the formation of vortices, the velocity distribution and the influence of the constructive parameters on the hydraulic performance are investigated. The study combines analytical methods with CFD simulations to identify the areas with energy losses and cavitation potential, providing hydromechanical optimization solutions. The results contribute to improving the design and operation of horizontal Kaplan turbines, with a direct impact on the efficiency and functional stability.
