并联管路流量分配的数值仿真研究

Numerical simulation of flow distribution of parallel pipeline system

通过建立典型的并联管路的物理模型,采用Fluent软件对并联管路的流量分布进行了数值仿真分析,研究了雷诺数和孔径比对支路管路流量分配的影响。结果表明,主管路雷诺数越小,支路管路的流量分配更均匀;孔径比越大,支路管路的流量分配更均匀。

By building the physical model of the typical parallel pipeline,the flow distribution of the parallel pipeline is numerically simulated via the Fluent software.The influence of Reynolds number and aperture ratio on the flow distribution of the branch pipeline is studied.The results show that the smaller the Reynolds number of the main pipeline,the more uniform the flow distribution of the branch pipeline,and the larger the aperture ratio,the more uniform the flow distribution of the branch pipeline.
