| Notes | 11-2047/S Closed-style pump sump is a kind of inlet structures of pump station. Bell-mouth, a part of axial-flow pump system, is used to adjust the velocity distribution on the inlet section of pump. The shape of bell-mouth is an important factor that can affect the hydraulic performance of pump system. In order to investigate the hydraulic performance of different shapes of bell-mouth,the three-dimensional fluid flow inside an axial-flow pumping system was simulated based on the Reynolds time-averaged Navier-Stokes equations, the RNG k-e turbulent flow model, the SIMPLEC algorithm and the law of the wall. The parameters values of closed-style pump sump were from literature including sump length, sump width, bottom clearance, back wall distance, and submergence depth. In order to exclude the possible influence from closed-style parameters, these parameters values were fixed based on design standard of sump. Seven schemes with different bell-mouth shapes were designed with that without bell-mouth as control（sch |
