| 摘 要： | 建立了纤维气流引导装置的3．D结构模型，应用计算流体力学软件ANSYSCFX对模型内气流场进行数值模拟，表征了引导装置内部三维流场的流动状态，分析了流场与纤维引导机制的相关关系，并考察喷射孔倾角对其内部流场流动特征的影响。结果表明：压缩气流经喷射孔后在纱道内形成三维旋转气流；切向速度沿纱道轴向与径向存在差异，会造成涤纶长丝上的捻度不匀；轴向速度在管壁附近处较大，涤纶长丝和纤维易与壁面碰撞。

| Abstract: | A three-dimensional computational fluid dynamics model was developed to simulate the flow field inside the fiber-guiding device with ANSYS CFX.Flowing state,distribution of static pressure and velocity and so on were characterized and analyzed.The relationship between flowing state and fiber-drawing was also discussed.The research shows that compressive air through the jet orifice comes into three-dimensional whirly airflow.The reason of twist irregularity of filament is that the tangential velocity at diff... |
