Accurate Determination of Volumetric and Mechanical Efficiencies and Leakage Behavior of Francis Turbine and Francis Pump-Turbine

Accurate Determination of Volumetric and Mechanical Efficiencies and Leakage Behavior of Francis Turbine and Francis Pump-Turbine
application/pdf In order to determine the volumetric and the mechanical efficiencies of Francis turbine and Francis pump-turbine, the flow in the front and the back spaces of a runner equipped with several thrust balancing devices, such as balancing pipes and balancing holes, is analyzed theoretically. The flow characteristics in sixteen types of model

Variable speed operations of Francis turbines

, 2019
Den økende andelen av uregulerbar kraftproduksjon, som vind og sol, blir det stadig viktigere å ha mer pålitelige energikilder for å tilfredsstille etterspørselen av et varierende strømforbruk.Vannkraft kan brukes til dette formålet, selv om dette ofte medfører å drive turbinen under forhold som den ikke var konstruert for.
