The analyses of the calendering processes using Oldroyd 8-constant fluid model with the
non-linear slip condition effects are discussed in this paper. To model the flow equations for …

John Vlachopoulos (JV) started his polymer processing career with the process of
calendering. In two landmark papers with Kiparissides, C. and Vlachopoulos, J.(1976). Finite …

This chapter is devoted to the presentation of the fundamental rheological properties of
polymers and their processing technologies. Measurements of the rheological properties …

Calendering is the process in which molten material is dragged through the nip region to
produce a film or sheet. By nip region, we mean the area between two corotating rolls. Here …

The aim of this paper is the investigation of heat transfer regarding the cases of both
stretching and shrinking sheets with a sponge-like horizontal wall that allows for mass …

A 3D flow analysis package is used to simulate the flow phenomena in a short section of the
metering zone of a single screw extruder. The assumption of stationary screw and rotating …

It has been known in the industrial sector that in closely intermeshing counterrotating twin
screw extruders, large separating forces develop in the calender gap, which push the …

To improve the plasticization quality and process safety of Modified Double-Base (MDB)
propellants during the calendering process. This study, using actual physical parameters of …

The frequent occurrence of safety accidents during the calendering process is caused by the
flammable and explosive properties of composite modified double-base (CMDB) propellant …

We investigate the effects of non-Newtonian parameters on the exiting sheet thickness in the
calendering of Oldroyd 4-constant fluid. The governing equations are first converted into …
