Prediction of runner eccentricity and Alford force of a Kaplan turbine based on variational mode decomposition

Prediction of runner eccentricity and Alford force of a Kaplan turbine based on variational mode decomposition

Abstract The rotor blades of an axial‐flow turbine are cantilever structures, and there is inevitably a gap between them and the casing. Due to factors such as rotor wear and unit vibration, the eccentricity of the impeller will change during the operation of the turbine, resulting in the impeller b...
