Computation of solid-fluid-fluid equilibria for binary asymmetric mixtures in wide ranges of conditions
(Elsevier Science, 2011-05)
In this work, we propose and test a numerical continuation method (NCM) for calculating solid-fluid-fluid (SFF) equilibrium loci for binary asymmetric systems. Such loci generally exist over a wide range of conditions. The ...
Test for the detection of the retrograde melting phenomenon in computed solid-fluid equilibria of binary asymmetric systems
(Elsevier Science, 2014-11-01)
The phenomenon of retrograde melting at constanttemperature takes place when a solid phase is melted, or made to disappear, upon compression. Analogously, retrograde melting at constant pressure happens when a solid phase ...
Equation of state modeling of the phase equilibria of asymmetric CO 2 + n-alkane binary systems using mixing rules cubic with respect to mole fraction
(Elsevier Science, 2010-12)
Both the equation of state (EOS) and the quadratic mixing rules proposed by van der Waals towards the end of the XIX century were enormous contributions to the understanding and modeling of fluids phase behavior. They set ...
Characterization of solid-fluid equilibrium regions of computed constant-overall-composition phase diagrams
(Elsevier Science, 2017-12)
In this work we studied the features of the solid-fluid region of computed binary constant-overall-composition phase diagrams (COCPDs), by resorting to calculated constant solidified-fraction curves. As generally done for ...
High pressure phase behavior modeling of asymmetric alkane + alkane binary systems with the RKPR EOS
(Elsevier Science, 2014-01)
Very asymmetric hydrocarbon mixtures present an interesting academic challenge for their modeling. In addition, they are becoming more important technologically, since the world oil reserves are becoming heavier in average. ...
Phase-separated symmetry-breaking vortex-lattice in a binary Bose-Einstein condensate
(2020-01-01)
We study spontaneous-symmetry-breaking circularly-asymmetric phase separation of vortex lattices in a rapidly rotating harmonically-trapped quasi-two-dimensional (quasi-2D) binary Bose-Einstein condensate (BEC) with repulsive ...
Stellar wind structures in the eclipsing binary system IGR J18027-2016
(EDP Sciences, 2021-03)
Context. IGR J18027-2016 is an obscured high-mass X-ray binary formed by a neutron star accreting from the wind of a supergiant companion with a ∼4.57 d orbital period. The source shows an asymmetric eclipse profile that ...
Modeling of solid-fluid equilibria of pure n-alkanes and binary methane + n-alkane systems through predictive correlations
(Elsevier Science, 2020-12)
In this work, we systematically study the phase behavior of the binary systems homologous series of methane with heavier n-alkanes, by considering the appearance of fluid and pure solid phases. The Peng-Robinson (PR) and ...
Prediction of double retrograde vaporization: Transitions in binary mixtures of near critical fluids with components of homologous series
(Elsevier Science, 2004-12)
The phenomenon of double retrograde vaporization (DRV) has been simulated using the group contribution equation of state coupled with the Michelsen computational procedures for calculating phase envelopes. This behavior ...
Dusty clumps in circumbinary discs.
(2019)
Protoplanetary discs are structures formed by gas and dust that form during the first stages
of the stellar evolution. Protoplanetary discs also are the birthplace of planets, moons,
and asteroids like the ones we observe ...
