Large-amplitude oscillatory shear flow from the corotational Maxwell model

AJ Giacomin, RB Bird, LM Johnson, AW Mix - Journal of Non-Newtonian …, 2011 - Elsevier
Using the single relaxation time corotational Maxwell fluid, we derive explicit analytical
expressions for the first, third, and fifth harmonics of the alternating shear stress response in …

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 …

Large-amplitude oscillatory shear: comparing parallel-disk with cone-plate flow

AJ Giacomin, PH Gilbert, D Merger, M Wilhelm - Rheologica Acta, 2015 - Springer
We compare the ratio of the amplitudes of the third to the first harmonic of the torque,,
measured in rotational parallel-disk flow, with the ratio of the corresponding harmonics of the …

Macromolecular origins of fifth shear stress harmonic in large-amplitude oscillatory shear flow

LM Jbara, AJ Giacomin, PH Gilbert - 日本レオロジー学会誌, 2017 - jstage.jst.go.jp
This study examines the simplest relevant molecular model of a polymeric liquid in large-
amplitude oscillatory shear (LAOS) flow: the suspension of rigid dumbbells in a Newtonian …

Transport phenomena in eccentric cylindrical coordinates

PH Gilbert, C Saengow, AJ Giacomin - AIChE Journal, 2017 - Wiley Online Library
Studies in transport phenomena have been limited to a select few coordinate systems.
Specifically, Cartesian, cylindrical, spherical, Dijksman toroidal, and bipolar cylindrical …

Converging shear rheometer

HM Baek, AW Mix, AJ Giacomin - Korea-Australia rheology journal, 2014 - Springer
For highly viscous fluids that slip in parallel sliding plate rheometers, we want to use a
slightly converging flow to suppress this wall slip. In this work, we first attack the steady …
