Chemical equilibrium with applications X program with user interface and visual basic programming
… the iterative method of minimizing the Gibbs energy or the Helmholtz energy first utilized in the NASA CEA program[1]. The original NASA CEA Program requires the use of FORTRAN compliers and knowledge of how to create program input files. The new CEA X Program uses Excel macros and user forms …

The Volumetric Properties for Selected Impurities in Dense CO2 Destined for Re-Injection
… the mixing coefficients for reference Helmholtz Energy Equations of State and Fluctuation Solution Theory models. The optimized mixing parameters were validated by comparison to existing density measurements and/or bubble / dew point data. Finally, the mixing coefficients were utilized …

Thermodynamic Formation Conditions for Propane Hydrates in Equilibrium with Liquid Water
… model for the hydrate phase and reduced Helmholtz energy equation for the fluid phases. Results are compared with highly variant literature data, where large deviations observed for the Lw-H-C3H8 (l) phase boundary can be mainly attributed to purity and experimental techniques used in the …

Properties Model for Aqueous Sodium Chloride Solutions near the Critical Point of Water
Traditional excess Gibbs energy models in terms of temperature, pressure, and concentration become progressively less effective in describing the thermodynamics of aqueous solutions at temperatures above 300 ¢ªC, and are totally inadequate in the critical region of water. This deficiency is due …

Finite-temperature many-body perturbation theory for electrons
… up to third order, to the electronic internal energy, chemical potential, grand potential, and entropy of an ideal gas of noninteracting, identical molecules in a wide range of temperature were determined numerically as the λ-derivatives of the respective quantity calculated exactly by a …
