Low Reynolds number flow theory finds wide application in such diverse fields as sedimentation, fluidization, particle-size classification, dust and mist collection, filtration, centrifugation, polymer and suspension rheology, flow through porous media, colloid science, aerosol and hydrosal technology, lubrication theory, blood flow, Brownian motion, geophysics, meteorology, and a host of other disciplines. This text provides a comprehensive and detailed account of the physical and mathematical principles underlying such phenomena, heretofore available only in the original literature.read more

Simulation of single fiber dynamics
TL;DR: In this paper, simulation results for the motion of flexible fibers modeled as rigid spheres connected by ball and socket joints are presented, showing that flexible fiber orientations drift in unbounded simple shear and parabolic shear flows.
Journal ArticleDOI
The sedimentation of a sphere through an elastic fluid. Part 1. Steady motion
TL;DR: Rajagopalan et al. as discussed by the authors compare finite element simulations and detailed point-wise experimental velocity measurements for the international benchmark problem of a sphere sedimenting axially under gravity through a cylindrical tube of viscoelastic fluid.
Journal ArticleDOI
Assessment of liquid water and gas permeabilities of partially saturated ordinary concrete
TL;DR: In this article, the authors presented an experimental study on relative gas and water permeabilities of ordinary concrete versus its saturation degree, which showed the influence of the saturation degree of concrete on the variation of water and gas permeabilities.
Journal ArticleDOI
Squirming through shear-thinning fluids
TL;DR: In this article, a spherical squirmer in a shear-thinning fluid was studied using a combination of asymptotic analysis and numerical simulations, and it was found that the rheology of the fluid can affect the swimming behavior of a squirming swimmer.

Multiparticle interfacial drag in equiaxed solidification
TL;DR: In this article, a physical model for the solid/liquid interfacial drag in both globular and dendritic equiaxed solidification is proposed, which is valid over the full range of solid volume fractions.
