الملخص الانجليزي
This paper is concerned with the numerical solution of polymer melt flows of both extrudate-
swell and tube-tooling die-extrusion coatings, using a hybrid finite element/finite volume
discretisation fe/fv. Extrudate-swell presents a single dynamic freesurface, whilst the
complex polymer melt coating flow exhibit two separate free-surface draw-down sections to
model, an inner and outer conduit surface of the melt. The interest lies in determining
efficient windows for process control over variation in material properties, stressing levels
generated and pressure drop. In this respect, major rheological influences are evaluated on
the numerical predictions generated of the extensional viscosity and Trouton ratio, when
comparing solution response for an exponential Phan-Thien Tanner (EPTT, network-based)
model to that for a single extended Pom-Pom (SXPP, kinematic-based) model.
