在对喷气织机主喷嘴分析现状的基础上，提出了CFD应用的思路。应用NUMECA软件对主喷管内部流动进行了数值模拟。揭示了螺纹管不同截面内的气流速度分布，分析了主喷管内气流的轴向动压和马赫数。结果表明，应用数值模拟方法研究主喷嘴内流场方便、快速、精度高。
Based on the current analysis status of main nozzle in air-jet loom, the idea of CFD application are put forward. The software of NUMECA is applied to simulate the flow inside of the main nozzle. The airflow velocity distribution in different cross-section of thread tube is also revealed, and the axial dynamic pressure and Mach number of air current inside of the main nozzle are analyzed. The result shows that the method of numerical simulation applied to research flow field inside of the main nozzles is convenient, rapid and high-accuracy.
