摘要/Abstract

摘要： 为了充分了解主喷嘴射流速度分布以便于优化喷气织机引纬系统的工艺参数，本文利用计算流体动力学软件Fluent对主喷嘴引纬流场进行数值模拟，得到主喷嘴出口射流中心线上的速度分布曲线及垂直于中心线的不同截面内流场的速度等值线图。为了验证数值模拟的合理性，通过实验获取了流场中不同点的速度，并与数值模拟结果做了分析比较，最终表明：在主喷嘴出口处速度实验测试值比数值模拟值小了约60m/s，随着流场延伸两者差距不断缩小，在距主喷嘴出口70mm以后两者具有较好的一致性。主喷嘴引纬流场的数值模拟结果在生产实践中值得借鉴。

Abstract: In order to fully understand the velocity distribution of jet flow of the main nozzle in an air-jet loom, which is used for optimizing the process parameters of weft insertion system, the numerical simulation based on weft insertion flow field of main nozzle is carried out by the computational fluid dynamics software called Fluent. The velocity distribution curve of the flow field centerline and the velocity distribution contour of the cross-sections which are perpendicular to the flow field centerline are obtained. In order to verify the rationality of numerical simulation, the speed of different points in the flow field has been got by the experiment. Finally by comparing the two results it’s indicated that experimental velocity is about 60m/s lower than simulative velocity at the outlet of the main nozzle, then the gap between them is shrinking as the flow field extends, and they are in good agreement since 70mm away from the outlet. So the simulative results deserve being referenced in practice.

Key words: main nozzle, flow field, Fluent, numerical simulation, air-jet loom
