Vibration Power Flow Modeling and Experimental Verification of a Multi-Substructure Centrifugal Pump Prototype

To enable consistent modeling and quantitative evaluation of vibration-energy transmission in centrifugal pumps with multiple coupled substructures and branches, this study develops a generalized transfer-matrix model. The method combines Craig-Bampton reduction with the four-terminal parameter method and the multibody...

Draft Tube Wake Vortex Evolution and Suppression in a Pump as Turbine with Splitter Blades Based on a Modified Burgers Vortex Model

Owing to its efficient energy recovery capability, the pump as turbine (PAT) has attracted considerable attention and has been widely applied in micro hydropower systems. However, under off-design conditions, large-scale helical vortex ropes are readily induced in the draft tube, causing severe hydraulic losses and flo...
