Analysis of the effect of flow channel structure on centrifugal accelerated motion of particles in vacuum state

This study explores the impact of flow channel structure on the acceleration of metal particles in a vacuum environment, aiming to enhance acceleration quality in centrifugal impact molding of metal powders. To assess this, three evaluation indices are introduced: the average speed of particles thrown 𝑉 𝑝 , the average speed of the particles 𝑉 𝑎𝑙𝑙 , and the particle velocity distribution 𝑉 𝑓 (t). The research analyzes how six distinct runner structures influence the centrifugal acceleration of particles. Findings indicate that the arc-shaped flow channel structure not only ensures a more consistent acceleration process but also results in a higher ejection speed, leading to an improved acceleration effect. This study's unique contribution is its examination of the relationship between flow channel design and particle acceleration in a vacuum.
