In fluid mechanics, the shear stress is calculated from the frictional force caused by viscosity and fluctuating velocity. Shear stress equations are used widely because of their simplicity. On the other hand, they have a critical limitation of requiring an energy gradient, which is generally ...

The shear stress, for a Newtonian fluid, at a surface element parallel to a flat plate, at the point y, is given by: where μ is the dynamic viscosity of the fluid; u is the velocity of the fluid along the boundary; y is the height above the boundary....

The minimum stress that is required to initiate flow is the static yield stress and the minimum stress that is needed to maintain flow is the dynamic yield stress [26,39]. Once the flow happens, the resistance offered by a fluid to flow freely is known as the plastic viscosity (µ). ...
Shear stress-driven flow: the state space of nearwall turbulence as Re τ→∞ 期刊名称: Journal of Fluid Mechanics 作者: Patrick Doohan,Ashley P Willis,Yongyun Hwang 年份: 2019年 关键词: Turbulent flows;nonlinear dynamical systems 摘要:An inner-scaled, shear stress-driven flow is considered ...
6). The elevated shear rates occur close to the tubing wall, whereas the fluid, which is in the center of the tubing, shows reduced shear stress exposure due to less exposure to friction. These individual “risk-zones” are reflected by the different particle counts and particle morphology ...
redistributed around the cell periphery, which was reflected in the distinct fluorescence intensity peaks located at the ends of the lines, indicating the periphery of the cell. Analysis of FN distribution after 24 hours of 6±3 dynes/cm2of fluid flow shear stress, (H) line 1–2 and ...
Alternatively, fluid shear stress has been applied to a 2D neuronal culture using a microfluidic chamber and a fast pressure servo. It is important to delineate that fluid shear as a loading mechanism is very different that shearing a 3D culture. Applying shear to a 3D culture creates a shape...
