英文摘要	The flow field in the intake and suction pipe of a pump station was simulated numerically by means of CFD software Fluent. In the computation, the finite volume method, 3D unstructured mesh and steady incompressible RNG k-Ε turbulence model were applied. Moreover, both the hydraulic loss and mass-weighted velocity uniformity at pipe inlet were optimized based on CFD simulations. To investigate the effect of vertical suction pipe position on flow pattern at the pipe inlet, the flow fields in the pump intake and suction pipe were simulated when the suction pipe was located at various positions in the pump intake which were specified by two parameters: one is the distance from the entrance to suction pipe to bottom of the pump intake, the other is the minimum distance between the outside wall of suction pipe to the side wall of the pump intake. Those parameters were expressed as a fraction of the inner diameter D of suction pipe according to the current pump intake design specifications. The velocity uniformity and hydraulic loss were correlated to the two parameters. The results indicated that in the large pump stations equipped with horizontal centrifugal pumps reasonable large two parameters can ensure the flow pattern at the pipe inlet uniform to prevent the pump intake from sand sedimentation and allow the pump to be operated efficiently and stably. The simulation results suggest that the minimum distance between the outside wall of suction pipe to the side wall of the pump intake and the distance from the entrance of suction pipe to bottom of the pump intake should be (0.4-0.8)D and (0.6-0.8)D, respectively, for reference in pump intake design.
