摘要:
入流竖井是排水深隧系统关键组成部分之一，选择合适的入流竖井类型直接影响着排水深隧系统的设计和运行。以武汉大东湖污水深隧工程中处理能力最大的二郎庙入流竖井为例，选择旋流式和折板式两种入流竖井进行对比，并采用realizable k-模型和SIMPLER算法分别对入流竖井中的流态、流速和压强等进行数值模拟分析。结果表明，在设计工况条件下，旋流式入流竖井在气液分离效果、整流效果、池体受力情况和消能效果等方面均优于折板式入流竖井，考虑到两类入流竖井在造价方面相差不大，故该工程采用旋流式入流竖井。
Abstract:
Drop shaft is one of the key components of deep drainage tunnel system. The selection of appropriate drop shaft type directly affects the design and operation of deep drainage tunnel system. This paper compared the performances of two types of drop shaft, namely vortex drop shaft and baffle drop shaft, and simulated the flow pattern, velocity and pressure in Erlangmiao drop shaft which has the largest treatment capacity in Dadonghu Wastewater Deep Drainage Tunnel Project in Wuhan by realizable k-ε model and SIMPLER algorithm. Under the design working conditions, the vortex drop shaft was superior to the baffle drop shaft in terms of gas-liquid separation, flow-stabilizing performance, shaft wall stress condition, and energy dissipation. Considering that the two types of drop shafts had little difference in investment, the vortex drop shaft was eventually selected for the project.
