Steady elongational flow from rotarance theory

MC Pak, AJ Giacomin, MA Kanso - Physics of Fluids, 2023 - pubs.aip.org
The physics of macromolecular orientation has been used to explain the elasticity of
polymeric liquids. Specifically, by first sculpting a rigid bead–rod likeness of the …

Analytical solution to calendering in eccentric cylindrical coordinates

P Poungthong, C Kolitawong, AJ Giacomin - Physics of Fluids, 2023 - pubs.aip.org
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 …

Wire coating and melt elasticity

P Poungthong, C Saengow, C Kolitawong… - Physics of …, 2024 - pubs.aip.org
In modern wire coating, the polymer is dragged through a round cylindrical die. Onto this
drag flow, we superpose pressure-driven extrusion. We devote this paper to analyzing this …
