An approach based on molecular dynamics results on Lennard–Jones spheres is proposed to model the viscosity of hydrogen sulfide, H 2S. The molecular parameters, that have a strong physical meaning, are the depth of the potential, and the length at which the potential is null (the "molecular...
Viscosity is an important fluid property when analyzing liquid behavior and fluid motion near solid boundaries. The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. The shear resistance in a fluid is caused by inter-molecular friction e...
The density and the dynamic viscosity · of the ternary mixture heptane+methylcyclohexane+1-methylnaphtaiene were measured at 303.15, 323.15 and 343.15K at atmospheric pressure for molar fractions xi =0, 0.125, 0.25, 0.375, 0.5, 0.625, 0.75, 0.875 and 1 (with i=1 3 xi = 1). The experim...
were calculated from each curve. Flow is the reciprocal of viscosity when integrated as a function of time between the starting time (t0) and the time to gellation (tgel). The test results for the viscosity tests at aheating rate of1 °C min−1are summarized inTable. 6. ...
Therefore the hydrogen bonds between the hydroxyl groups at chain ends, being surely present at C>0.6, is likely to affect the C dependence of the zero shear viscosity. It is probable that the hydrogen bonds may also affect the reaction rate constant K. Consequently, this effect is considered...
The viscosity behavior of this binary system is interpreted as the results of changes in the free volume and the breaking or weakening of hydrogen bonds. These data have been used to study the performance of two compositional models and a free-volume model. 展开 ...
Dynamic density functional theory (DDFT) is emerging as a useful theoretical technique for modeling the dynamics of correlated systems. We extend DDFT to quantum systems for application to dense plasmas through a quantum hydrodynamics (QHD) app
