“…When the pump unit is shut down due to sudden power failure or maloperation, it will eventually enter runaway mode, and when the pump unit is running in runaway mode, some parts of the pump unit may be damaged due to the mass imbalance of the rotating body and the hydraulic instability inside the unit [20]. More and more scholars have begun to conduct experiments and numerical simulation studies on the runaway mode of the pump unit [21,22]. Kan K et al [23] analyzed in detail the flow characteristics and energy loss of the internal flow field during the runaway process of an axial flow pump unit.…”

“…However, within the variable speed operation range of the centrifugal pump, unstable hump characteristics and cavitation phenomena often occur, shortening the pump's service life and reducing the reliability of its operation due to the generation of vibration and noise. Consequently, there are some restrictive technical problems involved in addressing the hump instability characteristic [3][4][5][6][7] and the cavitation characteristic [8][9][10][11][12][13] in the optimization design of the variable speed centrifugal pump.…”

“…In the coupling of all turbulence models, the SST γ-Re θt , in addition to the SST k-ω turbulence model, is the most widely utilized, not just for aerodynamics transition and separation prediction [28] but also in the field of hydraulics. Rahman [29], Zeng [30,31], and Ye [32,33] used the SST γ-Reθt to the boundary laminar flow of hydrofoil, which transits along the middle and low Reynolds numbers, and the transition of hydrofoil hydrodynamics is analyzed. However, the model needs to solve the batch factor equation and the transition criterion equation at the same time, and the calculation is slightly cumbersome.…”
