摘　　要：基于气动式紧密纺纱纤维集聚装置设计了气动式半紧密纺纱纤维集聚装置,采用大型流体计算软件模拟了气流在气动式紧密及半紧密纺纱纤维集聚区内的流动状态,并基于数值模拟结果分析了在气动式半紧密纺纱纤维集聚区内的气流流动状态与在气动式紧密纺纱纤维集聚区内的气流流动状态之间的差异。经分析认为:除增加了来自纤维集聚区前方的逆纤维运行方向的气流外,在气动式半紧密纺纱纤维集聚区内的气流流动状态与在气动式紧密纺纱纤维集聚区内的气流流动状态基本一致。Fiber condensing device of half compact spinning technology was designed based on fiber condensing device of compact spinning technology, a CFD technique was employed to simulate air flow inside fiber condensing zones of pneumatic compact and half compact spinning technology, and air flow patterns inside fiber condensing zones was analyzed depending on simulation results. The experiments indicated that air flow pattern inside fiber condensing zone of half compact spinning technology agreed with air flow pattern inside fiber conden- sing zone of compact spinning technology, except that air before fiber condensing zone flowed backward to movement of fiber strand.
