This study involved both numerical simulations and experimental investigations of the flow regime within the forebay of a large low-head pumping station, under conditions with and without partition walls. Using the Navier-Stokes equations and the equations for and of the RNG turbulence model, we conducted numerical simulations of the forebay. To validate these simulations, we added partition walls to the forebay and performed experiments on a physical model. The hydraulic characteristics under different operating conditions were tested to elucidate the mechanism by which partition walls optimize the flow regime. The analysis of the inlet flow regime revealed variations in hydraulic elements in the forebay with different partition wall lengths. Based on our findings, we proposed effective measures for improving the inlet flow regime, applicable to forebay design. These results are essential for developing more rational and sustainable operations of similar pump station forebay designs and optimizations.
