Wall shear stress and its role in atherosclerosis. [PDF]
Front Cardiovasc Med, 2023 Atherosclerosis (AS) is the major form of cardiovascular disease and the leading cause of morbidity and mortality in countries around the world. Atherosclerosis combines the interactions of systemic risk factors, haemodynamic factors, and biological factors, in which biomechanical and biochemical cues strongly regulate the process of atherosclerosis ...

Inner-outer decomposition of wall shear stress fluctuations in turbulent channels
Theoretical and Applied Mechanics Letters, 2022 Fluctuating wall shear stress in turbulent channel flows is decomposed into small-scale and large-scale components. The large-scale fluctuating wall shear stress is computed as the footprints of the outer turbulent motions, and the small-scale one is ...

Numerical investigation of blood flow in a deformable coronary bifurcation and non-planar branch [PDF]
BioImpacts, 2014 Introduction: Among cardiovascular diseases, arterials stenosis is recognized more commonly than the others. Hemodynamic characteristics of blood play a key role in the incidence of stenosis.

Model for Wall Shear Stress from Obliquely Impinging Planar Underexpanded Jets
Applied Sciences, 2022 Though inclined under-expanded planar jets are used in many practical applications, the wall stress resulting from their impingement has not been adequately characterized.

Science and Technology of Nuclear Installations, 2021 As two important parameters, the velocity of disturbance wave and the wall shear stress in annular flow are very important to solve the closed equations of the mechanical model for annular flow. In this study, the disturbance wave velocity and wall shear
