Mechanism of energy dissipation in cavitation vortices of low head axial flow pump-as-turbine via reduced-order variational mode decomposition
When the low head pump-as-turbine (PAT) mode, the nonlinear coupling of vortex systems (namely draft-tube and blade–passage vortices) and the intensification of cavitation degrade both efficiency and operational stability. Existing signal–decomposition techniques (e.g. EMD, EWT) struggle to disentan...
