  journal={arXiv: Fluid Dynamics},
This paper describes the isothermal die swell using our recent quasi-1D model for fast (high Deborah number) contraction flows of polymers melts. Because the model analyzes the flow in several flow regions as one continuous process, it makes possible to evaluate the die swell as a qusi-1D extrudate flow in dies of various lengths. Using the asymptotic matching condition for the change in flow type at the die exit allowed us to find the swelling profile for extrudate along the flow direction…

The Model of Fast Contraction Flows for Polymeric Melts

The present paper develops an isothermal model for fast (high Deborah number) contraction flows of polymers from a reservoir to a die of circular or rectangular cross-sections. Two components of

One dimensional simplification in modeling some basic polymer processing operations

Abstract In this work, we present a one-dimensional, simple model to describe extrudate swell manifested by polymeric liquid emerging from a circular die. The formulation established herein can

A theory of die‐swell

An elastic-fluid theory of die-swell for long dies is presented. The theory predicts a swelling ratio De/d asymptotically proportional, for large values of swelling, to the cube root of the

The present work deals with experimental and numerical features of entry flows of two polyethylene melts, namely a linear low-density polyethylene (LLDPE) and a low-density polyethylene (LDPE) in an

On the stretching and swelling of an elastic liquid extruded from a capillary die

A theoretical model for calculating the profile of a polymer jet extruded from a circular die and stretched by an axial force is elaborated. The model exploits the idea of matching the solutions for

Die Swell in Molten Polymers

The capillary flow properties of two commercial samples of polystyrene (Mw/Mn≈2.5–3.0) and three narrow distribution samples (Mw/Mn≈1.1) have been examined. Viscosity and extrudate diameter were

Swell and distortions of high-density polyethylene extruded through capillary dies

The effect of varying the die entrance angle and the die length on extrudate swell and on the onset of extrudate distortion in capillary extrusion has been studied. Using theory from the literature,
