摘要
为了探讨气流槽聚型集聚纺纱系统的集聚过程和机制,以气流槽聚型紧密集聚纺纱系统为基础,采用3D CFD技术建立了集聚区域的计算流体动力学模型,解析了集聚区域内流场的静压分布及速度分布规律。研究结果表明:须条进入凹槽入口前,只受气流集聚作用,当进入凹槽后,受到气流集聚及凹槽形状集聚共同作用;集聚区域内凹槽的气流分布并不均匀,越接近凹槽底部,气流的速度和静压分布变化波动较大,这主要是由集聚区圆孔的数目引起的。
To study the condensing process and mechanism analysis of compact spinning system with pneumatic groove,the computational fluid dynamic model was developed to simulate the flow field in convergence zone by 3D CFD technology based on the compact spinning system with pneumatic groove.Distributions of static pressure and velocity in convergence zone were analyzed.The results showed that the fiber bundle would be condensed only by the effect of airflow before it reached the groove and when sliding into the groove,it got effects from both airflow and shape of the groove;the fluctuation of the static pressure and velocity near the bottom of the pneumatic groove was relatively bigger and the number of the fluctuation was equal to the number of the round hole in convergence zone.
