Application of the compressible-dependent rheology to chute and shear flow instabilities

JS Fannon, IR Moyles, AC Fowler - Journal of Fluid Mechanics, 2019 - cambridge.org
We consider the instability properties of dense granular flow in inclined plane and plane
shear geometries as tests for the compressible inertial-dependent rheology. The model …

Mathematical modelling of subglacial bedform formation and dense granular flows

JS Fannon - 2020 - researchrepository.ul.ie
Subglacial bedforms, which include drumlins, ribbed moraine, and megascale glacial
lineations, are ubiquitous features in regions which were once covered by ice sheets, and …

An improved approximation for hydraulic conductivity for pipes of triangular cross-section by asymptotic means

LM Keane, CL Hall, IR Moyles - Journal of Engineering Mathematics, 2021 - Springer
In this paper, we explore single-phase flow in pores with triangular cross-sections at the
pore-scale level. We use analytic and asymptotic methods to calculate the hydraulic …
