摘　　要：为了探究管路系统内高速高压气流在流经不同形式接口时引起的下游支管流量重新分配问题,针对常见的三通、四通等接口类型,建立了相应的CFD模型,利用Fluent进行数值计算,研究了不同压力源、管径、接口形式对流量分配的影响。研究表明:管径比气源压力对接口流量分配更加敏感,下游接口的使用能够引起上游该支路流量占比增加,而自身接口处流量分配规律变化不明显。When the high-speed air flows through different interfaces in the pipeline system, the flow in the downstream branch pipe will be redistributed.Therefore, this paper established CFD simulation models of three-way and four-way, then numerical calculation was carried out by Fluent to study the influence of different pressure source, pipe diameters and interface forms on flow distribution.The results shows that the pipe diameter is more sensitive to the flow distribution of the interface than the pressure of the gas source. The use of the downstream interface can cause the flow proportion of the upstream branch to increase, but the change of the flow distribution law at the interface itself is inconspicuous.
