The Spatiotemporal Correlation Between Hydraulic Loss and Liutex-Based Vortex Dynamics Across Four Stall Regimes in a Pump-Turbine
Pumped-storage hydropower requires pump-turbines to operate safely and efficiently under off-design conditions, where stall-induced unsteady flows can redistribute hydraulic losses and reduce operational stability. Unlike previous analyses focused mainly on spatial correlations, this study develops a spatiotemporal fra...
