Abstract

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.
