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...

The shear viscosity for a heated granular binary mixture of smooth hard spheres at low density is analyzed. The mixture is heated by the action of an external driving force (Gaussian thermostat) that exactly compensates for cooling effects associated with the dissipation of collisions. The study is made from the Boltzmann kinetic theory, which is solved by using two complementary approaches. Fi...

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...

The formalism of conformal-solution theory (CST) has been extended to pure and mixed polar fluids with consideration of dipolar, quadrupolar and induced dipolar forces. The total potential energy is reduced to a form similar to that for neutral molecules by statistical averaging over orientations. The temperature dependence,s of the conformal parameters f, and h,, are derived and it is found th...

Recently, dimethyl ether (DME) has been paid much attention as a clean fuel. DME has many advantages as a substitute for liquefied petroleum gas (LPG). Sulfur oxides (SOx), and particulate matters (PM) are not produced at the combustion. Infrastructures and equipments for LPG can be used with slight improvements, because physical properties of DME are similar to those of light hydrocarbons, pro...

In a recent letter (C. Giraudet et al., EPL 111, 60013 (2015)) we reported preliminary data showing evidence of a slowing-down of non-equilibrium fluctuations of the concentration in thermodiffusion experiments on a binary mixture of miscible fluids. The reason for this slowing-down was attributed to the effect of confinement. Such tentative explanation is here experimentally corroborated by ne...
