摘要:
瓜洲泵站下游引河与古运河交汇区域水流流动较为紊乱,对船舶航行安全存在一定影响。通过CFD数值模拟可知,交汇区域以弯道水流进入下游引河,主流流速低于下游引河平均流速; 靠近瓜洲闸枢纽侧出现大尺度回旋,回流区水流平均流速在0.2 m/s以内,最大回流流速不超过0.35 m/s,且最大回流流速分布靠近翼墙圆弧段; 船舶航行靠岸侧区域的横向流速小于 0.15 m/s,纵向流速在0.5 m/s以内; 随着水深的增加纵横向水流流速有所下降; 交汇区域主流最大流速小于下游河床不冲流速,抗冲满足规范要求。分析成果对类似工程设计具有一定的参考价值。
Abstract:
The flow in the intersection of the river and the ancient canal at the downstream of the Guazhou pumping station was disordered, which had a certain impact on the navigation safety of ships.According to the numerical simulation of CFD, the intersection area entered into the downstream river by the curved water flow, and the mainstream flow rate was lower than the average flow rate of the downstream river.Large-scale cyclotron appeared near the hub of the Guazhou Sluice, the average flow velocity in the backflow area was within 0.2m/s, the maximum backflow velocity was no more than 0.35m/s, and the maximum backflow velocity distribution was close to the circular arc section of the wing wall.The transverse velocity of the ship in the berthing area was less than 0.15m/s, the longitudinal velocity was within 0.5m/s, and the transverse and longitudinal velocity decreased with the increase of water depth.The maximum flow velocity of the mainstream in the intersection area was smaller than the non-rushing flow rate of the downstream riverbed, and the impact met the specification requirements.The analysis results could have certain reference value for similar engineering design.
