and activation of blood elements. Critical levels of shear
exposure may be established in vitro thro...
Design Improvement of the Rotary Blood Pump by Computational Fluid Dynamics Analysis
artificial heart ventricular assist device axial flow blood pump computational fluid dynamics
2009/6/9
In this study, the pump performance derived from CFD analysis coincided well with the experimental results. From the results of the CFD analysis, the existence of reverse flows was found in the inflow...
Testicular blood flow and fluid dynamics in monkeys with surgically induced varicoceles
varicocele monkey testicular blood flow
2009/2/19
The blood flow rates and ability to remove an added fluid load were studied in the testes of monkeys with surgically induced varicoceles and in sham-operated control monkeys. These studies were conduc...
Capillary-Loaded Particle Fluid Dynamics：Effect on Estimation of Sperm Concentration
Spermatozoa capillary slide concentration hemacytometer Poiseuille Segre-Silberberg
2008/12/23
Capillary loaded chambers are frequently used for semen analysis. Poiseuille flow of specimen into these chambers causes migration of suspended particles or cells in a direction transverse to the ...
Influence on fluid dynamics of coronary artery outlet angle variation in artificial aortic root prosthesis
fluid dynamics coronary artery outlet angle variation artificial aortic root prosthesis
2010/2/25
Two simplified base geometries are used for simulating the blood flow in order to determine velocity and pressure distributions. One model uses a straight cylindrical tube to approximate the aortic ro...
Alterations in regional vascular geometry produced by theoretical stent implantation influence distributions of wall shear stress: analysis of a curved coronary artery using 3D computational fluid dynamics modeling
regional vascular geometry theoretical stent implantation a curved coronary artery 3D computational fluid dynamics modeling
2010/2/26
The current results predicting large spatial and temporal variations in WSS at specific locations in curved arterial 3D CFD simulations are consistent with clinically observed sites of restenosis. If ...
Axial stent strut angle influences wall shear stress after stent implantation: analysis using 3D computational fluid dynamics models of stent foreshortening
Axial stent strut angle 3D computational fluid dynamics models stent foreshortening
2010/2/26
The success of vascular stents in the restoration of blood flow is limited by restenosis. Recent data generated from computational fluid dynamics (CFD) models suggest that the vascular geometry create...
