Characterization 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 ...
Surface Strains of Porcine Tricuspid Valve Septal Leaflets Measured in Ex Vivo Beating Hearts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Quantification of the tricuspid valve (TV) leaflets mechanical strain is important in order to understand valve pathophysiology and to develop effective treatment strategies. Many of the traditional methods used to dynamically ...
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 ...
