Shape anisotropy-governed locomotion of surface microrollers on vessel-like microtopographies against physiological flows. [PDF]

Proc Natl Acad Sci U S A, 2021
Significance Controlled microrobotic navigation in blood vessels holds significant potential to revolutionize targeted drug delivery. Navigation on the surface of the blood vessels is advantageous because of decreased flow velocities; however, surface ...

An improved model for reduced-order physiological fluid flows [PDF]

, 2012
An improved one-dimensional mathematical model based on Pulsed Flow Equations (PFE) is derived by integrating the axial component of the momentum equation over the transient Womersley velocity profile, providing a dynamic momentum equation whose ...

Physiological non-Newtonian blood flow through single stenosed artery [PDF]

Theoretical and Applied Mechanics, 2016
A numerical simulation to investigate the Non-Newtonian modeling effects on physiological flows in a three dimensional idealized artery with a single stenosis of 85% severity is given. The wall vessel is considered to be rigid.

Head-to-head comparison of V-A ECMO, Impella and ECPELLA in normal ovine hearts [PDF]

Scientific Reports
Temporary mechanical circulatory support (MCS), including veno-arterial extracorporeal membrane oxygenation (ECMO) and micro-axial pumps (Impella), is increasingly used in clinical practice for refractory circulatory failure.

Fluid Analysis of Double-Layered Blood Flow through a Tapered Overlapping Stenosed Artery with a Porous Wall [PDF]

Journal of Heat and Mass Transfer Research, 2022
In this present work, we examine the fluid of double-layered blood flow through a tapered overlapping stenosed artery with a porous wall. This two-layered blood flow problem comprises the peripheral layer as Newtonian fluid flows and the central core ...

Reciprocating intestinal flows enhance glucose uptake in C. elegans

Scientific Reports, 2022
Despite its physiological and pathological importance, the mechanical relationship between glucose uptake in the intestine and intestinal flows is unclear. In the intestine of the nematode Caenorhabditis elegans, the defecation motor program (DMP) causes
