Intestinal villi and crypt density robustly maximizes nutrient absorption
Martin Garic, Rohan Vernekar, Dácil I. Yánez Martín +3
The villi and crypts of the gastrointestinal tract increase the effective surface area of the intestinal mucosa, potentially enhancing nutrient absorption. It is commonly assumed t…
Hydrodynamics in a villi-patterned channel due to pendular-wave activity
Rohan Vernekar, Faisal Ahmad, Martin Garic +4
Inspired by small intestine motility, we investigate the flow induced by a propagating pendular-wave along the walls of a channel lined with rigid, villi-like microstructures. The…
Margination of artificially stiffened red blood cells
Revaz D. Chachanidze, Othmane Aouane, Jens Harting +2
Margination, a fundamental process in which leukocytes migrate from the flowing blood to the vessel wall, is well-documented in physiology. However, it is still an open question on…
Comment on: In vitro prediction of the lower/upper-critical biofluid flow choking index and in vivo demonstration of flow choking in the stenosis artery of the animal with air embolism
Thomas Podgorski
In a recent paper published in Physics of Fluids, Sanal Kumar et al. present a model of transonic compressible flows based on ideal gas theory that is irrelevant to biofluid flow a…
Axial dispersion of Red Blood Cells in microchannels
Sylvain Losserand, Gwennou Coupier, Thomas Podgorski
Red Blood Cells flowing in a microchannel undergo dispersion in the flow direction due to the non-uniform velocity profile while transverse migration due to cell-wall interactions…
Rheology and structure of a suspension of deformable particles in plane Poiseuille flow
Vassanti Audemar, Thomas Podgorski, Gwennou Coupier
We present an experimental study of the rheology and structure of a confined suspension of deformable particles flowing in a quasi-two-dimensional Poiseuille flow. Thanks to a prec…
