Abstract An improved phase-partitioning model is proposed for the prediction of mutual solubility in CO2-brine system containing Na+, K+, Ca2+, Mg2+, Cl-, and SO42-. The correlations are computationally efficient reliable, they primarily designed incorporation into a multiphase flow simulator geology- energy-related applications including CO2 sequestration, CO2-enhanced geothermal systems, oil ...

The high calorific value of rice husk and rich silica content in ash make its valorization becomes attractive. This study presents the thermodynamics simulation performance combustion using a realistic decomposition approach. A non-ideal gas approach fugacity coefficient were also considered calculation. In this study, devolatilization is simulated to form (64.78%), liquid/tar (7.28%), solid/ch...

Abstract Garnet, an important mineral component in Earth's interior, usually contains minor water as structural OH, but experimental data on OH incorporation the a function of chemical and thermodynamic parameters remain rare. In particular, role oxygen fugacity ( f O 2 ) that is variable Earth has not been well assessed. We examine effects at 1–3 GPa 800–1000°C, by H‐annealing gem‐quality spes...

We consider the Asakura–Oosawa–Vrij model of hard sphere colloids and ideal polymer coils in contact with a planar hard wall at (colloidal) liquid–gas coexistence. Using extensive numerical density functional calculations, the liquid–gas, wall–liquid and wall–gas interfacial free energies are calculated. The results are inserted into Young’s equation to obtain the contact angle between the liqu...

In a recent paper with Bousquet-Mélou, de Gier, Duminil-Copin and Guttmann (2012), we proved that a model of self-avoiding walks on the honeycomb lattice, interacting with an impenetrable surface, undergoes an adsorption phase transition when the surface fugacity is 1 + √ 2. Our proof used a generalisation of an identity obtained by Duminil-Copin and Smirnov (2012), and confirmed a conjecture o...

Random coe cient regression models have been applied in di erent elds and they constitute a unifying setup for many statistical problems. The nonparametric study of this model started with Beran and Hall (1992) and it has become a fruitful framework. In this paper we propose and study statistics for testing a basic hypothesis concerning this model: the constancy of coe cients. The asymptotic be...

We consider two-component fermions with a zero-range interaction both in two and three dimensions calculate the bulk viscosity for an arbitrary scattering length high-temperature regime. evaluate Kubo formula using expansion respect to fugacity, which acts as small parameter at high temperatures. In zero-frequency limit of formula, pinch singularities emerge that reduce order fugacity by one. T...

Synopsis: The oxygen fugacity of the basaltic martian meteorites has been calculated from thermodynamic models involving spinel-ilmenite equilibria. The wide range of estimates, from near the IW buffer to near QFM, may be explained by mixing of mantlederived melts with oxidized material in the martian crust. Possible oxidized crustal end-members are considered. Analytical Method and Results: Sp...
