The wall shear stress produced by the normal impingement of a jet on a flat surface [PDF]
, 2000 A method for the theoretical determination of the wall shear stress under impinging jets of various congurations is presented. Axisymmetric and two-dimensional incompressible jets of a wide range of Reynolds numbers and jet heights are considered ...

Hemodynamics of Cerebral Aneurysm Initiation: The Role of Wall Shear Stress and Spatial Wall Shear Stress Gradient [PDF]
American Journal of Neuroradiology, 2011 Cerebral aneurysms are preferentially located at arterial curvatures and bifurcations that are exposed to major hemodynamic forces, increasingly implicated in the life cycle of aneurysms. By observing the natural history of aneurysm formation from its preaneurysm state, we aimed to examine the hemodynamic microenvironment related to aneurysm initiation

Vascular Wall Shear Stress in Clinical Practice
Current Vascular Pharmacology, 2007 Wall shear stress is a fluid dynamic quantity that is gradually emerging as a potentially important factor of coronary atherosclerosis. Methods, therefore, of estimation of shear stress in the arterial system are of clinical relevance. The purpose of this review is to define wall shear stress, review the various methods that have been used for its ...

A wall-shear stress predictive model [PDF]
Journal of Physics: Conference Series, 2011 Following the approach of Marusic et al. (2010b), here we develop a predictive model for the fluctuating wall-shear stress, where the only required input is large-scale information of the streamwise velocity at a location in the outer, logarithmic region of the flow.

Annular shear of cohesionless granular materials: from inertial to quasistatic regime [PDF]
, 2008 Using discrete simulations, we investigate the behavior of a model granular material within an annular shear cell. Specifically, two-dimensional assemblies of disks are placed between two circular walls, the inner one rotating with prescribed angular ...

On the measurement of wall shear stress with a patch-type micro-fabricated hot-film sensor
Journal of Fluid Science and Technology, 2014 In this study, a new patch-type hot-film sensor is devised to measure wall shear stress, and its measurement accuracy is validated. The sensor consists of heaters on a thin polyimide film and a flexible printed circuit.

Effect of Wall Shear Stress Gradient on Cells: Distribution of Deformation and Rotation [PDF]
Journal of Systemics, Cybernetics and Informatics, 2022 The effect of wall shear stress gradient on the deformation and rotation of each cell was investigated in vitro. To make a Couette-type of shear flow, the culture medium fluid was sandwiched with a constant gap between parallel walls: a lower stationary ...

Wall Orientation and Shear Stress in the Lattice Boltzmann Model
, 2012 The wall shear stress is a quantity of profound importance for clinical diagnosis of artery diseases. The lattice Boltzmann is an easily parallelizable numerical method of solving the flow problems, but it suffers from errors of the velocity field near ...
