A computational model for microcirculation including Fahraeus‐Lindqvist effect, plasma skimming and fluid exchange with the tissue interstitium

L Possenti, S Di Gregorio, FM Gerosa… - International Journal …, 2019 - Wiley Online Library
We present a two‐phase model for microcirculation that describes the interaction of plasma
with red blood cells. The model takes into account of typical effects characterizing the …

Dynamics of blood flow: modeling of the Fåhræus–Lindqvist effect

R Chebbi - Journal of biological physics, 2015 - Springer
To model the Fåhræus–Lindqvist effect, Haynes' marginal zone theory is used, following
previous works, ie, a core layer of uniform red blood cells (RBCs) is assumed to be …

Anomalous diffusion of deformable particles in a honeycomb network

Z Shen, F Plouraboué, JS Lintuvuori, H Zhang… - Physical Review Letters, 2023 - APS
Transport of deformable particles in a honeycomb network is studied numerically. It is shown
that the particle deformability has a strong impact on their distribution in the network. For …
