An expression for the viscosity of liquid metals has been derived using a theoretical model based on the theory of liquids. The equation is expressed in terms of fundamental physical parameters such as the pair distribution function and the time-averaged interatomic frequency. The equation ...
bitumen - diluent mixture viscosityA new method is presented for the correlation and prediction of the effect of temperature on viscosity of liquid hydrocarbons and their mixtures. A one-parameter viscosity-temperature equation is described that has been validated with data for approximately 360 pure ...
The Cassie–Baxter equation represents a contact angle at a surface that is composed of both solid and air because the liquid is prevented from fully penetrating into the pores of the surface due to its inherit repellence towards it which leaves air trapped in the roughness morphology. ...
A semi-theoretical model based on the classical Eyring's mixture viscosity equation and the Wilson activity coefficient equation is presented for correlating the viscosity of ionic liquids with solvent systems. The accuracy of the proposed model was verified by comparing calculated and experimental ...

A unified equation on the viscosity of pure liquid metals (published recently by the author) is combined with the well-known Sutherland – Einstein equation to obtain a new equation for the temperature dependence of the self-diffusion coefficients of pure liquid metals. The equation does not conta...

For the Poiseulle flow the shear stress and normal stress are calculated from the constitutive equation LCP-B, then the material functions such as apparent viscosity,the first and the second normal stress differences are obtained. For flow of the LCP fluid B, the change of the apparels ...
It is found that thermodynamic and mechanical definitions of the velocity field lead to different results in the active case, and that the density-dependent swimming speed of active particles gives rise to an effective viscosity of the active fluid. As a second main result, we show that active...
In 1906, Einstein [25] showed the viscosity of a suspension can be expressed as: (42)ηs=ηm(1+2.5ϕ) Eq. (42) is only valid when ϕ<1%. Ball [26] assumed that the effect of the particle in a concentrated suspension is the sum of the effect of the particle added sequentiall...
