We report the diffusion coefficient and viscosity of popular rigid water models: two non-polarizable ones (SPC/E with three sites, and TIP4P/2005 with four sites) and a polarizable one (Dang-Chang, four sites). We exploit the dependence of the diffusion coefficient on the system size (Yeh and Hummer 2004 J. Phys. Chem. B 108 15873) to obtain the size-independent value. This also provides an es...

Viscosity, a key property for glass processing, is a function of glass composition and temperature. Nuclear waste glasses must be formulated to obtain a desired viscosity at the melter processing temperature for each waste composition to be vitrified. Over the past decades, a large viscosity database has been accumulated at various laboratories in the US. The database, compiled at the Pacific N...

where η is the relative viscosity, φ the volume fraction of particles, B the Einstein coefficient (with a theoretical value B = 2.5), and α, β, γ are three adjustable parameters. The proposed parameterisation approximately reduces to the classical, well established relationships for small fractions. On the other hand, a weak point of equation (1) is that for large φ, the relative viscosity tend...

flow characteristics and rheological parameters of “malas yazdi” pomegranate (punica granatum l.) juice were investigated using rotational viscometer at different temperatures (10, 20, 30, 40, 50, 60 and 70ºc) and concentrations (12, 22, 32, 42 and 52º brix). the experimental data had the best fitness with herschel-bulkley model and the values of flow behavior index (n) varied between 0.97 and ...

The densities, ρ and viscosities, η of NH4Cl, NiCl2 and FeCl3 in dimethylsulfoxide were studied as a function of concentration. The partial molal volume, ( 0 v φ ) of these electrolytes were evaluated. The viscosity and viscosity-coefficients (A and B) were also determined by Jones-Dole equation. B-coefficient for NiCl2 and FeCl3 are positive that show structure making behavior in all the solut...

Background: In the high concentration of salts, kosmotropic and chaotropic effects became clear and these effects are related with Viscosity B-coefficient. Methods: In present study, the effects of high concentration of amino acid salts (1-3M) on yeast alcohol dehydrogenase was assessed and the effects of Na.Aspartate, Na.Glutamate. HCl.Glycinate, HCl.Lysinate and HCl.Lysinate on stability and ...

Thin jets of viscous fluid like honey falling from capillary nozzles can attain lengths exceeding 10 m before breaking up into droplets via the Rayleigh-Plateau (surface tension) instability. Using a combination of laboratory experiments and WKB analysis of the growth of shape perturbations on a jet being stretched by gravity, we determine how the jet's intact length l(b) depends on the flow ra...
