本文采用商用CFD（计算流体力学）软件包ANSYSCFX10.0对不同尺寸的圆形纱道内的流场进行了计算。相似放大的交织器的模拟结果显示出良好的协议与实验数据，除了一个强可压缩的流动区域。在强可压缩流区的模拟结果是大致一致的。然后，在相似的扩大交织器的流动模式是完全相同的，在实际尺寸的，以验证相似的扩大交织器。利用ANSYSCFX软件计算纱道内的流态，并对相似尺寸的网络器内的流态进行测量，具有一定的实用价值。在此基础上，分析了网络器圆形导纱管尺寸对气流组织的影响，并对网络器的性能进行了讨论。
In this paper, computation of flow patterns in circular yarn ducts with various sizes was performed using the commercial CFD (Computational Fluid Dynamics) software package ANSYS CFX 10.0. Simulated results of similarly-enlarged interlacers showed good agreement with experimental data except for a strongly compressible flow region. Simulated results in a strongly compressible flow region were in rough agreement. And then, flow patterns in similarly-enlarged interlacers were exactly the same as those in the practical-size ones to validate the similar enlargement of the interlacer. It is useful to use the ANSYS CFX for calculating the flow patterns in yarn duct and to measure the flow patterns in similarly-enlarged interlacers. On the basis of the simulated results, moreover, effects of size of circular yarn duct of interlacer on flow patterns were clarified and the performance of interlacer was discussed.
