The Influence of Hydraulic Characteristics on Structural Performance in a Pump-Turbine under No-Load Conditions

Shenming Ren,
Yuan Zheng,
Cong Yuan
et al.

Abstract: The operating state of a pump-turbine unit under no-load conditions is directly related to its safe and stable operation. In order to probe into the influence of hydraulic characteristics on structural performance, a pump-turbine assembled in China is selected for research by using CFD (computational fluid dynamics) and unidirectional FSI (fluid–structure interaction) methods. The vortex distribution and the law of pressure pulsation propagation are analyzed to capture the peculiar flow phenomena. The results … Show more
