RISCharacterization of Transition to Turbulence for Blood in a Straight Pipe Under Steady Flow Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Blood is a complex fluid that, among other things, has been established to behave as a shear thinning, nonNewtonian fluid when exposed to low shear rates (SR). Many hemodynamic investigations use a Newtonian fluid to ...
Impact of Blood Rheology on Transition to Turbulence and Wall Vibration Downstream of a Stenosis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: 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. ...
Transition to Turbulence Downstream of a Stenosis for Whole Blood and a Newtonian Analog Under Steady Flow Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: 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 ...
