Spatiotemporal modal dynamics and nonlinear characteristics of pressure fluctuations in a centrifugal pump under off-design operation

Off-design operation reorganizes centrifugal-pump pressure pulsations through interaction between the rotating impeller discharge and the stationary volute. To clarify how the non-uniform impeller-outlet pressure field is concentrated and modulated in the volute, unsteady computational fluid dynamics was performed at 0...

Vortex evolution and energy dissipation mechanisms under inlet distortion in a vertical inline pump based on Liutex and multiresolution dynamic mode decomposition

Inline pumps are widely used in space-constrained fluid transport systems, where energy efficiency and operational stability directly affect system safety and economy. The elbow-shaped inlet of a vertical inline pump can induce pronounced non-uniform inflow and alter the impeller inlet conditions. This study investigat...
