I'm currently working with the journal bearing model (Comsol 4.2) from the model library and I'm trying to calculate the shear stress within the fluid film with is an essential for the torque calculation. Unfortunatly the shear stress is not one of the output values of this module. I tri...
multi-fluid modelshear layershear stresssupercavity wallGas shear flows on a supercavity wall are an important part of inner structure for ventilated supercavitating flows, and gas in the shear layer enters wake flows to maintain mass balance of the gas inside supercavity. Understanding the shear ...
and a predictive formula of shear stresses of the BCT lattice structure model was established for the case of small shear deformation.Compared with the experimental data for different particle volume fractions, the theoretical results of the shear stress indicate the effects of the saturation ...
Shear stress is determined with the formula (3.2)τ=(6Qμ)/(wh2) where τ is shear stress, μ is fluid dynamic viscosity, Q is volumetric flow, w is chamber width, and h is chamber height. A variation of this chamber, called the Hele-Shaw chamber, is also in use (Usami et al.,...
In the relatively high flow environment of the arterial circuit, blood is a suspension that approximately behaves as a Newtonian fluid.8 This means that shear stress (τ) in a tubular chamber having radius r and flow direction z can be represented by the mathematical formula: τ = -μ(dvz/...
Shear stress may occur insolids or liquids; in the latter it is related to fluid viscosity. What is simple bending moment? A bending moment (BM) isa measure of the bending effect that can occur when an external force(or moment) is applied to a structural element. This concept is important...
This paper deals with the boundary shear stress distributions in trapezoidal open channels. The direction of the transport of surplus energy is discussed, which leads to the assumption that the surplus energy within any unit volume of fluid in 3-D flow will be transferred towards the nearest ...
The present invention relates to a biomedical implant for use in a fluid shear stress environment of a subject. The biomedical implant of the present invention includes a patterned
OSS group: the action of the syringe pump generated periodic fluid movement, which simulated oscillating shear stress, with an intensity of 0 ± 4 dyn/cm2. The calculation formula of shear stress is FSS = 6μQ/wh 2, where μ is the viscosity of the blood viscosity, Q (mL/min) is...
fluid density: viscosityempirical formulaeArid regions worldwide are plagued by collapsible soils. Collapsible soil is characterised by the sudden decrease in volume that occurs when it is subjected to inundation under constant stress. This volume change manifest itself as drastic and unpredicted ...
