剪切粘度即动力粘度，顾名思义，抵抗剪切变形的粘度，具体物理定义建议看书。做水下噪声的话，剪切粘度不...
We calculate the shear (η) and bulk (ζ) viscosities of a weakly coupled quark gluon plasma at the leading-log order with finite temperature T and quark chemical potential μ. We find that the shear viscosity to entropy density ratio η/s increases monotonically with μ and eventually scales...
The particles have temperature dependent masses arising from mean field or potential effects, which maintains self-consistency between the equation of state and the transport coefficients. As an example, we calculate the shear and bulk viscosity in the linear 蟽 \\sigma model. The ratio of shear ...
and blood vessels to move in such a way that blood flow may be interrupted, placing the patient at risk for pressure ulcers. An example of a shearing force is seen when a patient slumps in a chair; the skin around the buttocks is stretched by the movement and interferes with circulation....
Bayesian estimation of the specific shear and bulk viscosity of quark–gluon plasmaA consistent treatment based on the QCD sum rules at finite temperature has been established to calculate the J/Psi suppression in hot hadronic matter (HM) and quark-gluon plasma (QGP) respectively. We have found...
The pressure of the star, at the beginning of the collapse, is isotropic but, due to the presence of the shear viscosity and the bulk viscosity, the pressure becomes more and more anisotropic. The radial and temporal behaviors of the density, pressure, mass, luminosity, the effective ...
we are seeing normal stress and strain, where the force is perpendicular or normal to the box's surface. Along with normal stress and strain, two other common types are shear and bulk stress and strain. In this lesson, we'll go over both shear and bulk stress and strain and the equatio...
Here, we present thorough measurements with a small-amplitude linear atomic force microscopy technique and careful consideration of the confinement geometry, to show that in a weakly interacting liquid, average viscosity remains bulk like, except for strong shear thinning once the liquid is confined ...
where k is the complex wave number, k(ω)=k1(ω)+jk2(ω), and μ and η are the shear modulus and shear viscosity, respectively, defined previously. The shear wave velocity, cs(ω), and shear wave attenuation, αs(ω), are shown to be functions of μ and η by the relationships...
Ma, in Comprehensive Nanoscience and Technology, 2011 3.12.2.4.1(iv) Shear thinning For the liquid in the bulk and at sufficiently low shear rate, Newton’s law suggests that the response to the shear is linear, that is, the viscosity is a constant independent of the shear rate. As the...
