Effect of wall shear stress in the blood flow of two layers in the vessels through stenosis region
Wall shear stress Symmetric Stenosis Blood Flow of Two Layers
2010/9/27
In this paper the mathematical models have been developed to study the effect of wall shear stress in arteries of stenosis, where the blood flow is assumd to behave like a couple stress fluid, periphe...
Effect of Wall Shear Stress Distribution on Manning Coefficient of Smooth Open Rectangular Channel Flows
Open channel flow Manning friction coecient Wall shear stress
2009/10/12
The determination of velocity distribution in open channel flows is crucial in many critical engineering problems such as channel design, calculation of energy losses and sedimentation. In this study,...
Flow and wall shear stress in end-to-side and side-to-side anastomosis of venous coronary artery bypass grafts
Flow and wall shear stress venous coronary artery bypass grafts
2010/2/25
CFD analysis of venous CABG based on in-vivo CT datasets in patients was feasible producing qualitative and quantitative information on mass flow and WSS. Differences were found between the two types ...

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 ...
In-vivo coronary flow profiling based on biplane angiograms: influence of geometric simplifications on the three-dimensional reconstruction and wall shear stress calculation
In-vivo coronary flow profiling biplane angiograms
2010/2/26
We investigated the influence of two methods of lumen reconstruction, assuming circular versus elliptical cross-sections and using different resolutions for the cross-section reconstructions along the...
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

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...
The relationship between wall shear stress distributions and intimal thickening in the human abdominal aorta
wall shear stress distributions intimal thickening the human abdominal aorta
2010/3/1
The histomorphometric analysis suggests that IT increases with age and that the distribution of intimal thickening changes with age. The lowest WSS in the flow model was found on the posterior wall in...
