| 摘 要： | 船闸闸墙长廊道侧支孔充水具有不均匀性,影响闸室停泊条件。通过建立CFD数学模型,并经物模验证,研究闸墙长廊道侧支孔充水的水力特性及其对闸室自由水面运动的作用。结果表明,充水初期与后期的支孔流量分配规律相反,充水不均匀造成闸室水面长波运动。

| Abstract: | Water-filling is non-uniform by long culvert with branch orifices of shiplock,which impacts the mooring conditions of the lock chamber.Hydraulic characteristics of the process of water-filling by long culvert with side branch orifices and its influence on the free-surface movement of lock chamber are studied based on the CFD model and verified by the physical model.The results show that the law of flow distribution among orifices at thebeginning is opposite to which in the later period,and the non-uniform water-filling causes long wave on the free surface of lock chamber. |
