Three-dimensional CFD simulations of a pelletizing extruder were conducted using ANSYS Fluent to evaluate two polymers, A and B, under different thermal conditions. The area-averaged temperature and velocity at the polymer outlet were analyzed across 368 holes. Results indicate that Polymer A consistently exhibited higher outlet velocities compared to Polymer B under identical conditions, suggesting a greater tendency for long pellet formation. The influence of a \(25^{\circ }\text {C}\) free stream and oil channels was observed to reduce outlet temperatures, affecting flow behavior. These findings provide insight into defect tendencies and highlight the importance of thermal management in pelletizing operations.

摘要

Three-dimensional CFD simulations of a pelletizing extruder were conducted using ANSYS Fluent to evaluate two polymers, A and B, under different thermal conditions. The area-averaged temperature and velocity at the polymer outlet were analyzed across 368 holes. Results indicate that Polymer A consistently exhibited higher outlet velocities compared to Polymer B under identical conditions, suggesting a greater tendency for long pellet formation. The influence of a \(25^{\circ }\text {C}\) free stream and oil channels was observed to reduce outlet temperatures, affecting flow behavior. These findings provide insight into defect tendencies and highlight the importance of thermal management in pelletizing operations.
