Energetics of collapsible channel flow with a nonlinear fluid-beam model

DY Wang, XY Luo, PS Stewart - Journal of Fluid Mechanics, 2021 - cambridge.org
We consider flow along a finite-length collapsible channel driven by a fixed upstream flux,
where a section of one wall of a planar rigid channel is replaced by a plane-strain elastic …

Spatio-temporal relationship between three-dimensional deformations of a collapsible tube and the downstream flowfield

VN Bhargav, N Francescato, H Mettelsiefen… - Journal of Fluids and …, 2024 - Elsevier
The interactions between fluid flow and structural components of collapsible tubes are
representative of those in several physiological systems. Although extensively studied, there …

Instabilities in flexible channel flow with large external pressure

PS Stewart - Journal of Fluid Mechanics, 2017 - cambridge.org
We examine the stability of laminar high-Reynolds-number flow through an asymmetric
flexible-walled channel driven by a fixed upstream flux and subject to a (large) uniform …

MA Herrada, S Blanco-Trejo, J Eggers… - Journal of Fluid …, 2022 - cambridge.org
We consider the stability of flux-driven flow through a long planar rigid channel, where a
segment of one wall is replaced by a pre-tensioned hyperelastic (neo-Hookean) solid of …

Self-excited oscillations in a collapsible channel with applications to retinal venous pulsation

PS Stewart, AJE Foss - The ANZIAM Journal, 2019 - cambridge.org
We consider a theoretical model for the flow of Newtonian fluid through a long flexible-
walled channel which is formed from four compliant and rigid compartments arranged …

Experimental characterization of the oscillatory behavior of a quasi-two-dimensional collapsible channel

P Anderson, S Fels, S Green - Journal of Fluids and Structures, 2016 - Elsevier
Experiments are performed for a rigid, high-aspect-ratio, rectangular channel with a portion
of one wall replaced by a flexible membrane (a “2D” Starling resistor). The fluid is air, which …
