本文对插孔式分流器分流特性的影响因素进行了分析，找出分流器性能的三种结构影响因素。利用 CFD 模拟，分析了三种结构影响因素下的分流均匀性，并得到分流性能最好的各个结构参数的最优值。将三种结构参数进行组合，提出了六种新型插孔式分流器的结构，通过模拟得出其中最佳的结构。参照模拟得到的最佳结构加工了三个样件，并进行整机实验。结果表明，进出口各插入5 mm的深度和出口倾斜30°的分流器性能最佳；模拟能够准确预测分流器的性能。

The influence factors for Jack-type distributors were analyzed, and three structural influence factors for the distributor performance were found. By employing the CFD method, the diffluent uniformity under the conditions of the three structural influence factors was analyzed, and the optimized structural parameters corresponding to the best distribution characteristics were obtained. Six novel structures for the Jack-type distributor were proposed by combining the three structural parameters, and the optimized one was found out by simulation. Three samples for the optimized distributor based on the simulation results were produced, and were tested on the system experimental rig. The results show that, the diffluent characteristics of the distributor with inclination angle of 30° and insertion depth of 5mm is the best, and the simulation can predict accurately the performance of the distributor.
