喷水织机作为现代高效织造设备，其喷嘴结构对纬纱输送效率及织物质量具有关键影响。传统喷嘴存在牵引力不足、流场分布不均等问题，因而系统研究喷嘴流场特性对于优化结构、提升设备性能具有重要意义。基于计算流体力学数值模拟，构建不同喷嘴结构的流场模型，分析喷嘴几何参数对流场分布、流速变化及喷射角度等关键性能指标的影响。结果表明，合理优化喷嘴几何形状及锥度能显著改善流场特性并提升工作效率。当喷嘴锥角为50°时，喷射速度达到最大，牵引力最强，引纬效果最佳。
Abstract：As a modern high-efficiency weaving device, the nozzle structure of the water jet loom critically influences weft yarn delivery efficiency and fabric quality. Traditional nozzles suffer from insufficient tractive force and uneven flow field distribution; thus, systematic investigation of nozzle flow field characteristics is essential for structural optimization and equipment performance enhancement. Based on computational fluid dynamics(CFD) numerical simulation, flow field models with various nozzle structures were constructed, and the effects of nozzle geometric parameters on key performance indicators, including flow field distribution, flow velocity variation, and jet angle were analyzed. The results showed that rational optimization of nozzle geometry and taper can significantly improve flow field characteristics and enhance working efficiency. When the nozzle taper angle was 50°, the jet velocity reached its maximum, the tractive force was strongest, and the weft insertion performance was optimal.
