【摘要】：闸站结合布置方式结构复杂,泵站运行时前池易存在不良流态,降低泵站运行效率。以安徽某闸站结合工程为例,采用计算流体力学(CFD)对该工程进行模拟分析,研究其闸站工程布置的合理性和船舶通航的安全性以及改进优化方案。结果表明,原设计方案下的导流墩过短,导致斜流和回流的产生。针对原设计方案存在的不足,采取了2种导流墩优化方案,对2种优化方案改进的结果进行对比,发现仅对导流墩进行延长时,能减小前池内的回旋范围,降低通航的轴向速度,但横向速度的改善并不明显。而在导流墩延长的基础上,对导流墩进行开孔,能够降低通航的横向速度,保证闸站的稳定运行和安全通航。
[Abstract]:The structure of the sluice station combined with the layout is complex, and the bad flow state in the front pool of the pump station is easy to exist, which reduces the operation efficiency of the pump station. Taking a sluice station project in Anhui province as an example, this paper uses computational fluid dynamics (CFD) to simulate and analyze the project, and studies the rationality of the engineering layout of the gate station, the safety of ship navigation and the improvement of optimization scheme. The results show that the diversion piers in the original design are too short, which leads to the formation of oblique flow and reflux. In view of the shortcomings of the original design, two optimization schemes of diversion piers are adopted, and the results of the improvement of the two optimization schemes are compared. It is found that the circumflex range in the forebay can be reduced when only the diversion piers are prolonged. The axial velocity of navigation is reduced, but the improvement of lateral velocity is not obvious. On the basis of the prolongation of the diversion pier, the opening of the guide pier can reduce the lateral speed of navigation and ensure the stable operation and safe navigation of the sluice station.
