Three dimensional flow field numerical simulation and analysis of compact spinning with perforated rollers

This paper uses Fluent to carry out the numerical simulation of the compact area airflow of compact spinning with perforated rollers,evaluates the air current distribution visually,and quantitatively analyzes the distribution rules of velocity of the flow field in the compact zone and the impact of the distribution of the flow field on the strand structure.The results indicate that static pressure increases gradually from the wall of round hole to the centre of it,and the static pressure at air suction slot centre line is greater than that in other positions.The air movement is not isolated between two round holes,and the airflow of the lower position is affected more by round holes;and every axial velocity presents waviness with the emergence of the round hole at intervals.The airflow of higher position is more stable,without sudden change of axial velocity at intervals.
