The results show that the existence of the plasma layer may obviously change the wall shear stress and the wall shear stress gradient. Such as, the wall shear stress and the wall shear stress gradient decreases about 10% and 20%, when the thickness of the plasma layer being only 1% and 3% of the radius of blood vessel.
The simulating results demonstrate that it is very necessary to add a vacuum cavity or an air cavity beneath the hot-film of MEMS wall shear stress sensors.
The result indicated that,the pressure distribution at the compression phase (positive damper velocity)and rebound phase(negative damper velocity)are extremely similar which provided theoretic foundation for closed oil flow boundary shape design,and simultaneously calculated section flow orifice relationships between wall shear stresses and velocities,wall pressures and orifice length.
This paper refersed to Kelvin stress solution and gained the wall on pulling prestressed anchoring cable steel noose and shearing stress τ of the side panel, the paper also gained the shearing stress rand normal stress σ along axis of bore wall on compressing prestressed anchoring cable.
Wall shear stress in the bulge part of the channel shows smaller values that affect largely the rate of heat transfer and Nusselt number shows minimum values in this region.
Finally, the wall shear stress distributions on the side, top and bottom walls of the square duct with the Mach 4 pseudo-shock wave were investigated qualitatively by the shear stress-sensitive liquid crystal visualization method.
During a period, four secondary vortexes may exist on the circular cross-section and the distribution of axial velocity and wall shear stress are related to the ratio of the Coriolis force to centrifugal force and the axial pressure gradient.
Dynamic muscular exercise performed by healthy subjects leads to a rise in the left ventricular blood ejection with an acute increase in the local wall shear stress on the endothelium of the arterial vessels.
The velocity field and the wall shear stress have been calculated numerically by the finite element method to the time-dependent Navier-Stokes equations for pulsatile flow in a model of an aneurysm.
The second order perturbation results were obtained and the characteristics were analyzed at different time of the axial velocity, of the secondary flow, and of the wall shearing stress.
Theoretical results obtained for specific geometries are given for the velocity distribution, pressure drop, wall shearing stress, and separation phenomena.
