What is Anti-Swirl Fins in Francis Turbines about?
This study investigates the use of anti-swirl fins in a Francis turbine model to suppress vortex rope formation and pressure fluctuations at part load conditions with cavitation inception. The research demonstrates that longer fins significantly reduce swirl intensity and pressure peaks, enhancing turbine stability and efficiency. Numerical simulations and experiments validate the effectiveness of fin size and placement in mitigating cavitation-related issues, ultimately promoting safer turbine operation.
