Entropy Scaling for Viscosity of Pure Lennard-Jones Fluids and Their Binary Mixtures

چکیده
In this work, entropy scaling approaches for viscosity of pure Lennard-Jones (LJ) fluids and their mixtures have been investigated. To do so, we employed reliable database available in literature the LJ fluids, performed molecular dynamics simulation to generate over a wide range thermodynamic condition mixture fluids. It has shown that fluid, using macroscopic properties reduction yield noticeably better collapse data than one zero-density dense fluid region. addition, developed correlations based on these approaches. obtained predict with average absolute deviation around 4% more coming from low-density states, whereas it is 8.50% states other one. Finally, applied mixtures. Interestingly, are able provide good estimations all studied. However, deteriorates when employed.

Lennard-Jones Energy Parameter for Pure Fluids from Scaled Particle Theory
By considering the fact that the surface tension of a real fluid arises from a combination of both repulsive and attractive forces between molecules, a new expression for the interfacial tension has been derived from scaled particle theory (SPT) based on the work of cavity formation and the interaction energy between molecules. At the critical temperature, the interfacial tension between c...

متن کاملPhase diagrams of Lennard-Jones fluids
Smit and Frenkel’ have shown that the phase diagram of the two-dimensional Lennard-Jones fluid depends largely on the details of the truncation of the potential. In this Note, Gibbs-ensemble calculations are reported for the three-dimensional Lennard-Jones fluid. As expected, the phase diagram for this system also depends significantly on the details of the truncation. The Lennard-Jones potenti...
متن کاملVirial coefficients of Lennard-Jones mixtures.
We report results of calculations of the second through sixth virial coefficients for four prototype Lennard-Jones (LJ) mixtures that have been the subject of previous studies in the literature. Values are reported for temperatures ranging from T=0.6 to T=10.0, where here the temperature is given units of the LJ energy parameter of one of the components. Thermodynamic stability of the mixtures ...
متن کاملAnisotropic Lennard-Jones fluids in a nanochannel
During the past few decades molecular dynamics has been a widely applied tool to simulate fluid confined in micro/nano geometries. What makes interfacial fluids fundamentally different from the bulk fluid is the fact that their density varies considerably over microscopic distances. A class of such strongly inhomogeneous fluids are fluids confined in very narrow channels by solid boundaries. In...
