Numerical simulation on the condensing effect of suction slot in compact spinning with lattice apron

In this paper, a geometrical model is built by the actual structure of a condensing zone in compact spinning with lattice apron, and a fluid dynamics model is designed by FLUENT to study the numerical simulation of flow field in the condensing zone of straight, oblique, and deformed suction slots. The result shows the laws of airflow static pressure and velocity distribution of three kinds of condensing zones. The difference of distribution between compact direction and adsorption direction of strand is stressed on, which is helpful to make a deeper study on the mechanism of compact spinning with lattice apron and provide a theoretical support for the optimal design of suction slot.
