Influence of the flow rate on the die swell for polymer micro coextrusion process

A numerical model for a polymer double-layer single lumen microtubes coextrusion flow was constructed and the finite element method was used for numerical solution. The distribution of the velocity, pressure, shear rate, etc., were analyzed, as well as the relationship between the normal stress diff...
