Abstract:

The aim of the present work was to determine the flow characteristics of compressible airflow in the yarn channel of an interlacer by numerical simulations to make clear the effects of cross-sectional shapes of the yarn channel on the performance of interlacers. CFD (Computational Fluid Dynamics) software package ANSYS CFX was used to calculate flow patterns in the yarn channel. Relations between the performance of the interlacer and distribution of the velocity vector, airflow speed and particle trace of the flow were clarified to provide knowledge to design better interlacers.
