摘要
利用fluent软件对气流聚集型纺纱装置中的气体流场进行建模、分网、加载,得到气流流经尘笼及抽气孔处的速度矢量和压力分布图.说明了纤维在气流场中的运动规律,为如何合理有效地利用气流技术加工出质量好、成本低的产品,以及利用气流技术发展新工艺、新方法提供了可靠的理论基础.数值模拟与试验结果对比表明:数值模拟结果与实际情况比较吻合.数值计算还可以进一步优化气流聚集型纺纱装置的结构参数,通过气流集聚,绝大多数纤维被纺入纱线内,使纱线强度、抗磨性及抗断裂性能增强,纱线表面更光滑,改善了纱线的品质.
The fluent software was used to analyze gas flow field in flow aggregation-type spinning device by means of modeling, network division and loading, through which the distribution diagrams of velocity and pressure vector were drawn. The results calculated by Fluent well matched the experimental results. The motion law of fiber in flow field was interpreted theoretically, which provides reliable theoretical bases for how to make effective use of flow technology in fiber processing to produce good products with high quality and low cost, and for how to develop new technology and novel method. The numerical calculation can further optimize the structural parameters of flow aggregation-type spinning devices. Flow aggregation ensures that most of the fibers can be spun into yarns, which can strengthen the intensity, antiwear and anti-breaking properties of yams.
