High shear viscosity tests:Two types of friction reducers were prepared with distilled water at 0.10 wt%, 0.20 wt%, 0.40 wt%, 0.60 wt%, and 0.80 wt%. A Type 35 Fann six-speed viscometer was used to test the fluid viscosity at high shear rates. Low shear viscosity tests: According to...
The relationship between dilute gas shear viscosity and the anisotropy of simple linear molecules has been investigated. A corresponding states comparison of data for spherical and linear molecules, using Boyle properties as reducing parameters, showed some systematic changes of behaviour with increasing ...
Figure 1 shows the viscosity as a function of the Péclet number, that is, the rheology plot. All curves except for the reference system (i.e., 0 rigid bodies) exhibit shear thickening. The critical shear rate for shear thickening decreases when the volume fraction (or concentration) of the...
where \(\tau\) represents the shear stress, \(\mu _{0}\) the initial viscosity when the shear strain rate equals zero, \(\dot{\gamma }\) the shear strain rate, n a non-dimensional parameter controlling the fluid to be either shear-thinning or shear-thickening, \(\tau _{y}\) the...
摘要: Kovtun, Son and Starinets proposed a bound on the shear viscosity of any fluid in terms of its entropy density. We argue that this bound is always saturated for gauge theories at large 't Hooft coupling, which admit holographically dual supergravity description....

Shear viscosity measurements performed at low shear rates near the triple point of argon, krypton and xenon give results which agree with those obtained at higher shear rates. The non-newtonian behavior found in non-equilibrium molecular dynamics models seems to have no counterpart in the real flui...
A shear stress is applied to the particle surface by a flowing gas and the melamine beads circulate in a well-defined pattern following the fluid flow (Fig. 3d). Bead positions are monitored with an optical microscope and the viscosity of the host particle determined from the velocity of the...
