Theory and algorithms to compute Helfrich bending forces: a review

A Guckenberger, S Gekle - Journal of Physics: Condensed …, 2017 - iopscience.iop.org
Cell membranes are vital to shield a cell's interior from the environment. At the same time
they determine to a large extent the cell's mechanical resistance to external forces. In recent …

Anisotropic shear stress patterns predict the orientation of convergent tissue movements in the embryonic heart

F Boselli, E Steed, JB Freund, J Vermot - Development, 2017 - journals.biologists.com
Myocardial contractility and blood flow provide essential mechanical cues for the

Order–disorder transitions within deformable particle suspensions in planar Poiseuille flow

PC Millett - Journal of Fluid Mechanics, 2024 - cambridge.org
Three-dimensional simulations of the ordering of elastic capsule suspensions within planar
Poiseuille flow channels are reported. The simulations utilize the immersed boundary …

Hydrodynamic pairing of soft particles in a confined flow

O Aouane, A Farutin, M Thiébaud, A Benyoussef… - Physical review fluids, 2017 - APS
The mechanism of hydrodynamics-induced pairing of soft particles, namely closed bilayer

Global stability of flowing red blood cell trains

SH Bryngelson, JB Freund - Physical Review Fluids, 2018 - APS
A train of red blood cells flowing in a round tube will either advect steadily or break down
into a complex and irregular flow, depending upon its degree of confinement. We analyze …

Non-modal Floquet stability of capsules in large-amplitude oscillatory extensional flow

SH Bryngelson, JB Freund - European Journal of Mechanics-B/Fluids, 2019 - Elsevier
We analyze the stability of a capsule in large-amplitude oscillatory extensional (LAOE) flow,
as often used to study the rheology and dynamics of suspensions. Such a flow is typically …

Irregular dynamics of cellular blood flow in a model microvessel

SH Bryngelson, F Guéniat, JB Freund - Physical Review E, 2019 - APS
The flow of red blood cells within cylindrical vessels is complex and irregular, so long as the
vessel diameter is somewhat larger than the nominal cell size. Long-time-series simulations …
