Wall Shear Stress and Early Atherosclerosis

American Journal of Roentgenology, 2000
therosclerosis remains the leading cause of morbidity and mortality in the Western world [1, 2]. It is usually regarded as a systemic disease and several well-identified risk factors (i.e., hypertension, hyperlipidemia, diabetes mellitus, and cigarette smoking) have been implicated in its pathogenesis.

Wall shear stress in stenotic artery

Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 1992
The effects induced by a mild arterial stenosis on the wall shear stress is theoretically investigated. Distribution of shear stress along canine femoral artery and during the cardiac cycle is calculated simulating both the physiological state of the artery and the stenotic condition.

Wall shear stress in collapsed tubes

The European Physical Journal Applied Physics, 1999
A small flexural wall rigidity brings unique features to cross-sectional shapes and blood flow within veins, which are characterised by a non-uniform hemodynamical environment acting upon endothelial cells. Velocity fields and related wall shear stress were numerically determined for a large number of conditions, assuming a fully developed, steady ...

Preliminary measurements of wall shear stress

International Communications in Heat and Mass Transfer, 1999
Abstract This paper presents the investigation of wall shear stress of the fluid flow in the clearance gap between the impeller face and inlet casing of a blood pump model. This was accomplished through hot-wire anemometry and rotating disk apparatus.

Shear Stress around Vertical Wall Abutments

Journal of Hydraulic Engineering, 1998
Shear stress distribution around vertical wall abutments is studied experimentally, and maximum shear stresses that occur at the upstream corner of vertical wall abutments are determined. Shear stress distributions are presented for Froude numbers ranging from 0.30 to 0.90 and for protrusion ratios (ratio of protrusion length perpendicular to direction

A new wall shear stress gauge

Experiments in Fluids, 1989
A new technique has been developed to measure the wall shear stress and its direction in a turbulent boundary layer. This technique involves the measurement of torque upon a very small cylindrical body placed above the wall deep in the viscous sublayer, so that the device is operating in the creeping flow regime.

[Wall shear stress and endothelium].

Casopis lekaru ceskych, 2005
Blood flow influences the luminal side of vessel wall by a frictional force known as wall shear stress (WSS). This local hemodynamic factor is an important determinant of endothelial gene expression and of endothelial phenotype. The effect of WSS depends on its magnitude and direction, as well as on the characteristic of vessel geometry and blood flow.

Determination of arterial wall shear stress

Science in China Series A: Mathematics, 2001
The arteries can remodel their structure and function to adapt themselves to the mechanical environment. In various factors that lead to vascular remodeling, the shear stress on the arterial wall induced by the blood flow is of great importance. However, there are many technique difficulties in measuring the wall shear stress directly at present.

Wall shear stress in accelerating turbulent pipe flow

Journal of Fluid Mechanics, 2011
AbstractAn experimental study of wall shear stress in an accelerating flow of water in a pipe ramping between two steady turbulent flows has been undertaken in a large-scale experimental facility. Ensemble averaged mean and r.m.s. of the turbulent fluctuations of wall shear stresses have been derived from hot-film measurements from many repeated runs ...
