Abstract：In this paper,the flow and water distribution uniformity in the box culvert of an urban drainage pump-ing station with slanted intake in Shanghai was studied numerically based on the unsteady Reynolds averaged N-S equation and the RNG k-ε turbulence model.The results showed that the oblique inflow could easily cause an unequal water distribution in different box culvert channels of the urban drainage pumping station,and that there were some adverse flow patterns such as backflow,vortex flow,transverse flow,found in the gate shaft,some box culvert channels and the fore-bay of the pumping station.The flow pattern and water distribution uniformity in the box culvert could be improved by a thorough design and setting a new typical rectification measure in the gate shaft.And there would be good inflow condition in the pumping station.The results of this paper could pro-vide some valuable references to design and operation of urban drainage pumping station with slanted intake.
