Fluid mechanics of papermaking

F Lundell, LD Söderberg… - Annual Review of Fluid …, 2011 - annualreviews.org
Papermaking is to a large extent a multiphase flow process in which the structure of the
material and many of the relevant properties of the final product are determined by the …

Jeffery's orbits and microswimmers in flows: A theoretical review

K Ishimoto - Journal of the Physical Society of Japan, 2023 - journals.jps.jp
In this review, we provide a theoretical introduction to Jeffery's equations for the orientation
dynamics of an axisymmetric object in a flow at low Reynolds number, and review recent …

Shape-dependence of particle rotation in isotropic turbulence

buoyant spheroid suspended in a simple shear flow, valid for arbitrary particle aspect ratios …

Comparison of erythrocyte dynamics in shear flow under different stress-free configurations

D Cordasco, A Yazdani, P Bagchi - Physics of Fluids, 2014 - pubs.aip.org
An open question that has persisted for decades is whether the cytoskeleton of a red blood
cell is stress-free or under a stress. This question is important in the context of theoretical …

Effects of inertia and viscoelasticity on sedimenting anisotropic particles

V Dabade, NK Marath, G Subramanian - Journal of Fluid Mechanics, 2015 - cambridge.org
An axisymmetric particle sedimenting in an otherwise quiescent Newtonian fluid, in the
Stokes regime, retains its initial orientation. For the special case of a spheroidal geometry …

Motion of spheroid particles in shear flow with inertia

W Mao, A Alexeev - Journal of fluid mechanics, 2014 - cambridge.org
In this article, we investigate the motion of a solid spheroid particle in a simple shear flow.
Using a lattice Boltzmann method, we examine individual effects of fluid inertia and particle …

Orbital drift of capsules and red blood cells in shear flow

D Cordasco, P Bagchi - Physics of Fluids, 2013 - pubs.aip.org
Many numerical studies have considered the dynamics of capsules and red blood cells in
