摘要：

为提高喷气织机引纬性能，降低能耗，对辅助喷嘴结构及其参数进行优化研究。采用数值模拟分析方法，利用 Fluent 软件，研究了辅助喷嘴不同结构及参数对辅助喷嘴出口处的气流速度、速度衰减以及耗气量的影响规律。为得到喷射性能好且耗气量低的辅助喷嘴结构，提出了评定辅助喷嘴综合性能的方法。结果表明：中心环形分布方式的辅助喷嘴喷射性能优于环形分布的辅助喷嘴；相同孔数的中心环形分布的辅助喷嘴，其出口风速随中心孔直径减小而减小，相同喷孔面积条件下，耗气量随喷孔数目的增加呈现递减趋势，8K04 型辅助喷嘴耗气量最低； 7K04 型辅助喷嘴喷射速度高，且耗气量低，综合性能最优； 5K03、6K05、7K04、8K04 型辅助喷嘴的综合性能优于单圆孔辅助喷嘴。

Abstract:

In order to improve the weft insertion performance of the air-jet loom and reducing the energy consumption, the structures and parameters of the auxiliary nozzle were optimized. By numerical simulatio analysis, using Fouent software, the influence of different sructures and parameters of the auxiliary nozzle on airflow velocity, velocity attenuation and air consumption at the outlet of the auxiliary nozzle were investigated. A method for evaluating the comprehensive comparison of the auxiliary nozzle was proposed to obtain an auxiliary nozzle with good injection performance and low air consumption. The results show that the injection performance of the auxiliary nozzle with the center annular distribution mode is better than that with the annular distribution. The auxiliary nozzle of same orifice number with the center annular distribution has the outlet airflow velocity decreasing with the decrease of the center orifice diameter. Under the same orifice area, air consumption of the auxiliary nozzle decreases gradually with the increase of nozzle oridice number, and the air consumption of 8 K04 auxiliary nozzle is minimum. It is found that the comprehensive performance of 7 K04 auxiliary nozzle is the best with high airflow velocity and low air consumption. The comprehensive performance of 5 K03, 6 K05,7 K04 and 8 K04 auxiliary nozzles are better than that of single circular orifice auxiliary nozzle.
