Analysis of Bubble Growth in Supercritical CO<sub>2</sub> Extrusion Foaming Polyethylene Terephthalate Process Based on Dynamic Flow Simulation

Analysis of Bubble Growth in Supercritical CO<sub>2</sub> Extrusion Foaming Polyethylene Terephthalate Process Based on Dynamic Flow Simulation

Bubble growth in the polymer extrusion foaming process occurs under a dynamic melt flow. For non-Newtonian fluids, this work successfully coupled the dynamic melt flow simulation with the bubble growth model to realize bubble growth predictions in an extrusion flow. The initial thermophysical proper...
