Gas phase adsorption of binary mixtures on planar walls in dispersive systems was studied by molecular dynamics simulations, extending a previous study the pure components. The interactions between all particles, fluid as well solid, were described Lennard-Jones truncated and shifted potential with cutoff radius 2.5 σ. Two classes studied: (a) symmetric mixtures, which components also their wal...

We investigate the dynamical behavior of binary fluid systems in two dimensions using dissipative particle dynamics. We find that following a symmetric quench the domain size R(t) grows with time t according to two distinct algebraic laws R(t) ∼ t: at early times n = 1 2 , while for later times n = 2 3 . Following an asymmetric quench we observe only n = 1 2 , and if momentum conservation is vi...

in the present work, the integral equations method is used to calculate transport properties of polar fluids. for this goal, we use the stockmayer potential and examine theoretically the thermal conductivity of several refrigerant mixtures such as r125+r134a, r125+r32, r125+r152a, r134a+r32, r152a+r32, r134a+r143a, and r125+r143a. we solve numerically the ornstein-zernike (oz) equation using th...

the effect of magnetic field on the liquid-liquid equilibrium of two ternary systems (water + acetic acid + butyl acetate and water + acetic acid + dimethyl succinate) at 298.15 k under atmospheric pressure was investigated. the results obtained show that the strength of the magnetic field (0.02 t) affects the solubility of acetic acid in the used organic solvents. distribution coefficients and...

The molecular interaction volume model (MIVM) developed by Tao is a fluid-based derived from statistical thermodynamics and fluid phase equilibria. MIVM was applied successfully to predict each element’s activity in Mn-based alloys, namely, Mn-C Mn-Fe, Mn-Fe-C systems. calculated binary parameters between metals (Fe, Mn) nonmetal (C) confirming strong Fe Mn alloy. indicated that iron has great ...

– The phase behavior of binary fluid mixtures of hard hyperspheres in four and five dimensions is investigated. Spinodal instability is found by using a recent and accurate prescription for the equation of state of the mixture that requires the equation of state of the single component fluid as input. The role played by the dimensionality on the possible metastability of the demixing transition...

Abstract The SAFT‐γ Mie model is a recent version of statistical associating fluid theory (SAFT), which uses group contribution approach to obtain high‐quality equation state. In this work, is, for the first time, extended ionic liquids (ILs). calculated values agree well with experimental data one‐component, binary and ternary systems that contain ILs, thus indicating versatility accuracy exte...

Recently Khasare derived an equation of state for L-J fluid by modifying an expression for work done, obtained from partition function through perturbation approach .This is achieved by inserting at some fixed position in the m-component fluid, a single solute particle of radius ‘R’ in n-dimensions along with the necessary thermodynamic requirements. It was therefore thought worthwhile to under...
