Numerical study of two-dimensional air flow in spinning cup of rotor spinning

Modeling and meshing of airflow field in the spinning cup of air-extracting type rotor spinning were carried out by using the computational fluid dynamics software FLUENT,and two-dimensional numerical simulation of flow field in the cup was conducted by finite volume method,obtained the velocity vector distribution and the X-axis direction and Y-axis direction speed of two sections.The results revealed the flow characteristics in the cup,the flow speed was between 20 m/s and 150 m/s,and the velocity distribution of the section also illustrated the movement trend of the fiber,thus verifying the feasibility of the FLUENT software in research of the airflow in spinning cup.
