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 …

Extruding plastic pipe from eccentric dies

C Saengow, AJ Giacomin, C Kolitawong - Journal of Non-Newtonian Fluid …, 2015 - Elsevier
To solidify plastic pipe, the pipe is transported through a long cooling chamber. Inside this
chamber, inside the pipe, the plastic remains molten, and this inner surface solidifies last …

Knuckle formation from melt elasticity in plastic pipe extrusion

C Saengow, AJ Giacomin, C Kolitawong - Journal of Non-Newtonian Fluid …, 2017 - Elsevier
When plastic pipe is solidified, it proceeds through a long cooling chamber. Inside the

Polymer process partitioning: Extruding plastic pipe

C Saengow - 2016 - search.proquest.com
When plastic pipe is solidified, it proceeds through a long cooling chamber. Inside this
chamber, inside the hollow extrudate, the plastic is molten, and this inner surface solidifies …

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 …

Fluid elasticity in plastic pipe extrusion: Loads on die barrel

C Saengow, AJ Giacomin - International Polymer Processing, 2017 - degruyter.com
In large thick plastic pipe extrusion, the residence time in the cooling chamber is long, and
the melt inside the pipe sags under its own weight, causing the product to thicken on the …

Viscous dissipation of a power law fluid in axial flow between isothermal eccentric cylinders

C Kolitawong, N Kananai, AJ Giacomin… - Journal of non …, 2011 - Elsevier
We study the temperature distribution of a power law fluid in a pressure-driven axial flow
between isothermal eccentric cylinders in bipolar cylindrical coordinates. We begin our …

Transport phenomena in bispherical coordinates

PH Gilbert, AJ Giacomin - Physics of Fluids, 2019 - pubs.aip.org
The practice of transport phenomena has traditionally been confined to Cartesian,
cylindrical, spherical, and bipolar cylindrical. For just the equations of continuity and motion …
