New insight into prediction of phase behavior of natural gas hydrate by different cubic equations of state coupled with various mixing rules
Gas Hydrate, Cubic equation of state Mixing rule Thermodynamic modeling
2018/4/2
Progress in hydrate thermodynamic study necessitates robust and fast models to be incorporated in reservoir simulation softwares. However, numerous models presented in the literature makes selection o...
A mechanistic model of heat transfer for gas–liquid flow in vertical wellbore annuli
Gas–liquid flow Vertical annuli Heat transfer Tubing liquid film Casing liquid film
2018/4/2
The most prominent aspect of multiphase flow is the variation in the physical distribution of the phases in the flow conduit known as the flow pattern. Several different flow patterns can exist under ...
Dilute Bose gas with correlated disorder: a path integral Monte Carlo study
Dilute bose gas thermodynamics integral monte carlo method the continuous space superfluids quantum
2014/12/19
We investigate the thermodynamic properties of a dilute Bose gas in a correlated random potential using exact path integral Monte Carlo methods. The study is carried out in continuous space and disord...

Recent landmark experiments have demonstrated how quantum mechanical impurities can be
created within strongly correlated quantum gases and used to probe the coherence properties of these systems [1]...
Effective Width and Expansion Energy of the Interacting Condensed 87Rb Bose Gas with Finite Size Effects
Interacting Bose gas Thermodynamical properties for BEC Semiclassical approach
2010/4/8
This work is devoted to study the temperature dependence of the effective width and expansion energy on the finite size and interaction effects (repulsive interactions). It is found that the effective...

Thermodynamics an Ideal Gas of Bosons State and Susceptibilities
2010/10/14
We present theoretical aspects concerning the thermodynamics of an ideal bosonic gas trapped by a harmonic potential. Working in the Grand Canonical ensemble we are able to properly identify the exten...
Adiabatic Output Coupling of a Bose Gas at Finite Temperatures
Adiabatic Coupling Bose Gas Finite Temperatures
2010/10/15
We develop a general theory of adiabatic output coupling from trapped, weakly-interacting,
atomic Bose-Einstein Condensates at finite temperatures. For weak coupling, the output rate from the condens...
