Shear dependence of effective cell volume as a determinant of blood viscosity.
TLDR
The viscosity of suspensions of human erythrocytes was measured over a wide range of shear rates, and the macrorheological data were correlated with the micror heological behavior of ery throatcytes and rigid particles.Abstract:
The viscosity of suspensions of human erythrocytes (normal cells in plasma, normal cells in Ringer's solution containing albumin, and hardened cells in Ringer's solution containing albumin) was measured over a wide range of shear rates, and the macrorheological data were correlated with the microrheological behavior of erythrocytes and rigid particles. The formation of rouleaux increases the effective volume of erythrocytes as a result of (i) the increase in axial ratio and (ii) the limitation of deformation of individual erythrocytes. The effective cell volume is the fundamental determinant of blood viscosity.read more

Blood flow in arteries
TL;DR: The study of arterial blood flow will lead to the prediction of individual hemodynamic flows in any patient, the development of diagnostic tools to quantify disease, and the design of devices that mimic or alter blood flow.

TL;DR: New convection models have been developed to predict clinical from platelet thrombosis in diseased arteries, and future hemodynamic studies should address the complex mechanics of flow-induced, large-scale wall motion and convection of semisolid particles and cells in flowing blood.

Flow-induced clustering and alignment of vesicles and red blood cells in microcapillaries.
TL;DR: This model combines a particle-based mesoscale simulation technique for the fluid hydrodynamics with a triangulated-membrane model and shows that already at very low HT, the deformability of RBCs implies a flow-induced cluster formation above a threshold flow velocity.

The formation of emulsions in definable fields of flow
TL;DR: The physical and chemical condition of emulsions of two fluids which do not mix has been the subject of many studies, but very little seems to be known about the mechanics of the stirring processes which are used in making them.

The viscosity of a concentrated suspension of spherical particles
TL;DR: In this paper, the authors extended the viscosity equation for an infinitely dilute suspension of spheres to apply to a suspension of finite concentration, and made use of a functional equation which must be satisfied if the final viscosities is independent of the sequence of stepwise additions of partial volume fractions of the spheres to the suspension.

Fluid Drop-Like Transition of Erythrocytes under Shear
H. Schmid-Schönbein,Roe E. Wells +1 more
TL;DR: Red cells dispersed in a continuous medium of high viscosity possess the flow properties of fluid drops, while under shear they become progressively deformed into prolate ellipsoids, their long axis aligned parallel to the flow direction.
