Implication

In vitro curved artery models capture secondary flows; extends pulsatile hemodynamics characterization but leaves open in vivo translation.

Non-Newtonian blood-analog fluid rheology

Newtonian blood-analog fluid
O
Outcome
Secondary flow structures and vortical structure formation

Non-Newtonian blood-analog fluid rheology alters vortical structures and decreases mean pressure losses in a 180° curved artery model compared to Newtonian fluids.
