On the Thermodynamics of Strongly Degenerate Two‐Component Plasmas

physica status solidi (b), 1986
AbstractA generalisation of Gell‐Mann‐Brueckner's formula is derived for two‐component systems of charged particles with any mass ratio and multi‐valley degeneracy. Higher order rs‐contribution are determined in the random phase approximation. Numerical values are given especially for hydrogen plasmas and for optically excited electron—hole plasmas in ...

Thermodynamic Properties of High-Temperature Air Components

1996
The paper gives a synthetic description of the basic methods to calculate the high-temperature thermodynamic properties of air species. Emphasis is given to the strong dependence of the electronic partition function and the thermodynamic properties of atomic species on the number of electronic levels taken into account.

Components and Thermodynamic Cycles

2019
Although many technical components, that are required to run energy conversion processes, have already been discussed previously, the focus in this chapter is on thermal turbo-machines as well as on heat exchangers. However, in this chapter the technical components are treated in steady state operation.

The Thermodynamics of One-Component and Two-Component Elastic Systems

Textile Research Journal, 1950
The thermodynamic analysis of stress in one-component, one-phase elastic systems is reviewed, and it is suggested that the stress be evaluated in terms of entropy and enthalpy contributions. The analysis is then extended to two-component, two-phase systems, and the necessary equations are derived.

Thermodynamic modeling of dilute components in multicomponent solutions

Calphad, 2009
Abstract Those performing applied calculations with thermodynamic database computing systems often find that an essential component of a particular solution phase is missing from the database. Provided that one is interested only in dilute solutions of this component, and only over a relatively narrow concentration range of the major components, the ...

Determination of volatile components of systems not in thermodynamic equilibrium

Talanta, 1987
A review is given of the literature on the analysis of complex mixtures of organic compounds and a procedure proposed for the separation and identification of the components of such mixtures. Retention data obtained with several chromatographic columns are combined with information from mass and Fourier-transform infrared spectra and identifications ...

Thermodynamic studies of a HAT cycle and its components

Applied Energy, 2012
The electric power grid contains more and more renewable power production such as wind and solar power. The use of renewable power sources increases the fluctuations in the power grid which increase the demand for highly efficient, fast-starting power-producing units that can cope with sudden production losses.

Statistical Thermodynamics of the Transition Region between Two Phases. II. One Component System with a Plane Interface

, 1952
An approximate statistical theory is used to investigate the nature of the density transition curve in passing from a one component liquid phase to the equilibrium vapor phase.

On the derivation and application of solution thermodynamics for reactive components

Fluid Phase Equilibria, 1982
Abstract A formulation of the procedure for the application of chemical theory to the problem of calculating the thermodynamic properties of apparent components in a solution from those of the true species in the solution is presented. This formulation is simpler than the general unifying mathematical analysis previously available.

On the Crystallography and Thermodynamics in Orientationally Disordered Phases in Two-Component Systems☆

, 1997
The experimental two-component phase diagram between the orientationally disordered crystals 2-amino-2-methyl-1,3-propanediol (AMP) and 1,1,1-tris(hydroxymethyl)propane (PG) has been established from room temperature to the liquid state using thermal ...
