摘　　要：在ANSYSCFX中建立了船坞排水系统的三维模型,分别计算并得到了3种不同工况下的排水管路及泵入口处的流型、速度云图及速度矢量分布,验证了防涡流装置的性能及必要性,确保排水系统高效稳定运行。研究思路及计算方法对国内外的类似工程有一定的指导意义。The three-dimensional model of the dock drainage system is established in ANSYS CFX.The flow pattern,ve⁃locity contours and velocity vector distribution of the drainage pipeline and the pump inlet under three different working conditions are calculated and obtained.The performance and necessity of the anti-vortex device is verified to ensure the effi⁃cient and stable operation of the drainage system.The research ideas and calculation methods have certain guiding signifi⁃cance for domestic and foreign engineering.
