对带"品"字型导流均流墙的T型连接井交汇水流进行数值模拟计算,分析了连接井内的流态、流速分布等,结论证明,"品"字型导流均流墙能使来水在连接井内改变方向,从而均匀地进入下游三孔箱涵,圆弧设计对于水力流动影响较小,基本不增加水头损失。
Abstract:A numerical simulation is made on the confluence at the guide-walls in a triangle-layout in the junction chamber,and then the flow pattern,flow velocity,etc.in the chamber are analyzed.The conclusion shows that the guide-walls in a trianglelayout can make the inflowing water changing its direction in the chamber and thus evenly flow into the downstream tri-box culvert;for which the design of circular arc has less impact on the hydraulic flow with non-loss of the water head basically.
