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...

Digital twin architectures for industrial pumps: Integrating data perception, reduced-order modeling, and implementation paradigms

Comprehensive analysis indicates that the interdisciplinary integration of multisource data fusion and non-intrusive reduced-order modeling synergistically improves real-time responsiveness while preserving the physical fidelity of fluid-dynamics knowledge.
