Low wall shear stress predicts subsequent development of wall hypertrophy in lower limb bypass grafts [PDF]
Artery Research, 2009 Background: Venous grafts commonly develop myointimal hyperplasia, which can lead to stenoses and, ultimately, with expression of adhesion molecules, lumenal occlusion.

Simple shear flow of a Herschel-Bulkley fluid with wall slip above a threshold stress
Applications in Engineering Science, 2021 The simple shear flow of Herschel-Bulkley fluids is analyzed, under the assumption that wall slip occurs at both plates above a characteristic wall shear stress, the slip yield stress.

Machine Learning-Based Segmentation of the Thoracic Aorta with Congenital Valve Disease Using MRI
Bioengineering, 2023 Subjects with bicuspid aortic valves (BAV) are at risk of developing valve dysfunction and need regular clinical imaging surveillance. Management of BAV involves manual and time-consuming segmentation of the aorta for assessing left ventricular function,

Shear stress fluctuation measurements using an electrochemical method in pipe flow
Journal of Fluid Science and Technology, 2019 Wall shear stress fluctuations are measured using an electrochemical method in pipe flow. The relationship between the mass transfer and the momentum transfer, studied by Hanratty and Campbell (1983) and the Chilton–Colburn analogy (Chilton and Colburn ...

Development of a Flexible MEMS Sensor for Subsonic Flow
Micromachines, 2022 Detection and control of flow separation is a key to improving the efficiency of fluid machinery. In this study, we developed a flexible MEMS (microelectromechanical systems) sensor for measuring the wall shear stress and flow angle in subsonic airflow ...

Reconstructing wall shear stress from thermal wall imprints
International Journal of Heat and Fluid Flow, 2022 We reconstruct the wall shear stress of plane Couette flow from thermal wall imprints generated by direct numerical simulation at using an imposed surface temperature flux and fixed temperature at the bottom and top boundary, respectively. We explore the strong correlation between wall shear stress and wall temperature by analysing their joint ...

Aortic wall shear stress in Marfan syndrome [PDF]
Magnetic Resonance in Medicine, 2012 The aim of this study was to quantify changes in thoracic aortic wall shear stress (WSS) in asymptomatic patients with Marfan syndrome (MFS) compared with healthy controls. WSS in the thoracic aorta was quantified based on time‐resolved 3D phase contrast MRI with three‐directional velocity encoding (4D flow MRI, temporal resolution ∼44 ms, spatial ...
