We are concerned here with the effect of added filler particles on the linear and non-linear
rheological properties of viscoelastic systems. Whilst the addition of spherical or near …

The effect of viscoelasticity on multilayer polymer extrusion is discussed. In these
coextrusion processes predetermined patterns are created with a remarkable breadth of …

The relevance of upstream contraction for extrudate swell behavior of polymer melts is
numerically investigated for slit dies with an aspect ratio of 10 and a length-to-height ratio …

The second normal stress difference N 2 experienced by non-Newtonian fluids flowing in a
pipe may give rise to secondary flows in the transverse direction. As a result, one component …

This paper is concerned with the investigation of stratified flows of viscoelastic fluids by three-
dimensional numerical simulation. The aim is to elucidate the mechanism behind the …

The present paper shows the applicability of phase-field modeling to three-dimensional
stratified flows of viscoelastic fluids. As already pointed out by Yue et al.[P. Yue, C. Zhou, J …

采用Giesekus 本构方程, 建立了预测方形截面共挤口模中两种聚合物熔体层间界面形状和位置
的三维黏弹数值模型, 利用polyflow 进行了数值求解, 将计算结果同Karagiannis …

A three-dimensional viscoelastic numerical simulation was developed for a two-layer
coextrusion through a rectangular channel by using the finite element method. The Phan …
