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 …

Co-extrusion has become the state-of-the-art process technology in nearly all application
areas of polymer processing. By combining different types of polymeric materials within …

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

Computer simulations of polymer foaming processes in extrusion flow have been carried out
in order to improve current understanding of viscoelasticity and bubble growth effects on die …

This work presents a numerical method for solving three-dimensional (3D) viscoelastic
unsteady free surface flows governed by the Oldroyd-B constitutive equation. It is an …

In the co‐extrusion of plastics, pressure‐throughput behavior, layer distribution, and
residence time are crucial parameters, modeling of which contributes to manufacturing high …

In this study, we numerically investigate the hydromagnetic three dimensional flow of a
radiating Maxwell fluid over a stretching sheet embedded in a porous medium with heat …

An attachment suitable for any standard torsional rheometer is described; it extends the
capability of the rheometer, thereby enabling simultaneous measurement of the first (N 1) …

The nonlinear transient dynamics and stability of a two-dimensional (2-D) model of the
isothermal film casting process have been investigated using newly devised simulation …

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 …
