Abstract Phase equilibrium data ( $$p$$ p , $$T$$ T $$y$$ y ) for the binary systems of carbon dioxide + dimethyl carbonate and ethyl methyl were obtained. All measured isotherms ranging from 298.2 K to 328.2 with pressure between 0.13 MPa 10.6 MPa. A static technique was establi
The isotropic-nematic and nematic-nematic phase transition of binary mixtures of tangent hard-sphere chain fluids: an analytical equation of state.
An analytical equation of state (EoS) is derived to describe the isotropic (I) and nematic (N) phase of linear- and partially flexible tangent hard-sphere chain fluids and their mixtures. The EoS is based on an extension of Onsager's second virial theory that was developed in our
On the critical non-additivity driving segregation of asymmetric binary hard sphere fluids
A previously proposed version of thermodynamic perturbation theory, appropriate for singular pair interactions between particles, is applied to binary mixtures of hard spheres with non-additive diameters. The critical non-additivity DC required to drive fluid–fluid phase separati
Densities and Viscosities of Mixtures of Two Ionic Liquids Containing a Common Cation
Density and dynamic viscosity data of binary mixtures of ionic liquids (ILs) were determined in this work, at temperatures from 283.15 to 363.15 K and at 0.1 MPa. The mixtures of two ILs comprise a common cation and different anions, combining 1-butyl-3-methylimidazolium bis(trif
High-pressure phase equilibrium and volumetric properties of pseudo-binary mixtures of stock tank oil + methane up to 463K
High-pressure phase equilibrium and volumetric properties of highly asymmetric mixtures related to reservoir fluids are critical the development high-pressure high-temperature (HPHT) reservoirs. However, there is a lack relevant data accurate modeling tools. In this work, we prep
Towards the phase diagram of a polydisperse mixture of charged hard spheres
– In an effort to approach a quantitative determination of the phase diagram of polydisperse mixtures of (possibly size-asymmetric) charged hard spheres (CHS), we propose a concept that explicitly takes into account the association of the ions into dimers, i.e., an effect that is
A Numerical Modeling of a Variable Conductance Thermosyphon by Use of a Binary Mixture
In this paper the steady state performance of a variable conductance heat pipe, which its working fluid consists of two components (R11+ R113) is modeled. The role of the liquid film momentum and axial normal stresses are considered by use of the mean property of mixture and the
Experimental and molecular modeling study on the binary mixtures of [EMIM][BF4] and [EMIM][TFSI] ionic liquids
The properties of [EMIM][BF4] + [EMIM][TFSI] double salt ionic liquid (DSIL) were studied as a function mixtures composition and temperature. Experimental physicochemical combined with molecular simulation (quantum chemistry classical dynamics) considered, thus providing micro ma
Hamiltonian Principle in Binary Mixtures of Euler Fluids with Applications to the Second Sound Phenomena
In the present paper we compare the theory of mixtures based on Rational Thermomechanics with the one obtained by Hamilton principle. We prove that the two theories coincide in the adiabatic case when the action is constructed with the intrinsic Lagrangian. In the complete thermo
Phase behaviour of a symmetrical binary mixture in a field
– Integral equation theory calculations within the mean spherical approximation (MSA) and grand canonical Monte Carlo (MC) simulations are employed to study the phase behaviour of a symmetrical binary fluid mixture in the presence of a field arising from unequal chemical potentia
