Previous experimental flow studies have demonstrated a delay (∼20%) in transition to turbulence for whole blood compared to a Newtonian analog fluid in both a straight pipe and eccentric stenosis model with ridged walls. The impact of wall complian

Blood, a multiphase fluid comprised of plasma, blood cells, and platelets, is known to exhibit a shear-thinning behavior at low shear rates and near-Newtonian behavior at higher shear rates. However, less is known about the impact of its multiphase n

Dissertation/ Thesis

Transition to turbulence within an eccentric stenosis geometry under steady flow using laser Doppler vibrometry for a non-Newtonian and Newtonian fluid

Autor: Rayanne, Pinto Costa

The blood flow inside the human is mostly laminar[4]. However, complex geometries (such as stenoses and arteriovenous grafts) can cause turbulence in the flow [16,6]. Stenosis is a narrowing of the artery wall, which can cause heart attacks and strok
