基于ADINA流固耦合的纤维在涡流场中的运动研究
Study on Motion of Fiber in Vortex Flow Field Based on ADINA Fluid Structure Interaction
摘要
Abstract
To study the fiber movement in air jet vortex spinning,the 2D computational model based on MVS 861 air jet vortex spinning was developed;By using the fluid-solid interaction calculation module in the finite element calculation software ADINA,analysis result of the fiber air two-phase interaction was obtained,in the meanwhile,the influence of the pressure at the nozzle hole on the two-phase flow was studied.Simulation results show that air is ejected from the jet orifice,the vortex field is generated in the flow field and the internal fiber is pushed in a wave motion toward the nozzle exit.With the increase of the pressure at the nozzle,the fiber′s period of movement becomes shorter and the frequency of fiber′s oscillation frequency increases.Increasing the pressure at the nozzle hole can improve the work efficiency of twisting and wrapping of the fiber.关键词
