摘要/Abstract

摘要：

为提高喷气织机引纬性能,采用数值模拟分析方法,利用Fluent软件研究了延伸喷嘴的不同结构及参数对其导纱管内气流速度、气流场稳定性的影响,并对延伸喷嘴结构及其参数进行优化。结果表明:延伸喷嘴最后一个辅喷嘴出口与其纬纱入口的最佳距离应在60 mm左右,距离太大或者太小都会导致导纱管内轴向气流速度减小;延伸喷嘴进气口与纬纱入口最佳距离应在30 mm左右,距离太小会使导纱管内气流场不稳定,距离太大会使导纱管内速度提升不明显;当延伸喷嘴喷射角度在10°左右时,气流速度径向分布的标准偏差最小,导纱管内气流场较为稳定。

Abstract:

In order to improve weft insertion performance of air-jet loom, the structure and parameters of extended nozzle were optimized. The influence of different structures and parameters of the extended nozzle on the airflow velocity and stability of the airflow field in the guide tube of the extended nozzle was studied by means of numerical simulation analysis and Fluent software. The results show that the optimum distance between the last auxiliary nozzle outlet and the weft inlet of the extended nozzle is about 60 mm, too large or too small distance will lead to the decrease of the axial airflow velocity in the guide tube, and the optimum distance between the extended nozzle inlet and the weft inlet is about 30 mm, too small distance will cause the airflow field in the guide tube unstable, and too large distance will cause the speed increase in the guide tube not obviously. When the spray angle of the extended nozzle is about 10°, the air flow field in the guide tube is relatively stable.

Key words: air jet loom, auxiliary nozzle, extended nozzle, numerical simulation, airflow field
