Magnetocombustion: A Thermodynamic Analysis

Journal of Propulsion and Power, 2000
The impact of a uniform magnetic e eld on equilibrium combustion characteristics has been explored. An expression for the Gibbs free energy, which includes a magnetic e eld contribution, has been developed. Using the method of Lagrange multipliers, changes in the Gibbs free energy for a mixture of paramagnetic and diamagnetic ideal gases are minimized.

Thermodynamic analysis of manganese

International Journal of Thermophysics, 1990
A description of the Gibbs energy of the various solid modifications of manganese at 101325 Pa has been obtained for the whole temperature range from 298 K to the melting point. The present analysis accounts for the effect of a magnetic transition in α-, γ-, and δ-Mn, which is treated using the Inden-Hillert-Jarl phenomenological model for the magnetic

Thermodynamic analysis of spectra

AIP Conference Proceedings, 2008
Although random matrix theory had its initial application to neutron resonances, there is a relative scarcity of suitable nuclear data. The primary reason for this is the sensitivity of the standard measures used to evaluate spectra—the spectra must be essential pure (no state with a different symmetry) and complete (no states missing).

Thermodynamic Analysis of the Darcy Law

Journal of Applied Mechanics, 1961
The Darcy law is used extensively to describe the flow of fluids through porous media. According to this law the fluid flow is linearly dependent upon the pressure gradient and the gravitational force. The proportionality factor is generally known as the permeability of the porous medium.

A thermodynamic analysis of solvation

The Journal of Chemical Physics, 1988
The free energy, energy, and entropy of solvation, relative to the pure liquid, are analyzed. By a coupling parameter integration it is shown that only averages over the solute–solvent interaction energy contribute to the free energy and that the solvent–solvent interaction term, which contributes the so-called cavity (solvent reorganization) term to ...

Thermodynamic DFT analysis of natural gas

Journal of Molecular Modeling, 2017
Density functional theory was performed for thermodynamic predictions on natural gas, whose B3LYP/6-311++G(d,p), B3LYP/6-31+G(d), CBS-QB3, G3, and G4 methods were applied. Additionally, we carried out thermodynamic predictions using G3/G4 averaged.

Microtextured superhydrophobic surfaces: A thermodynamic analysis

Advances in Colloid and Interface Science, 2007
Superhydrophobic surfaces with a contact angle (CA) larger than 150 degrees have recently attracted great interest in both academic research and practical applications due to their water-repellent or self-cleaning properties. However, thermodynamic mechanisms responsible for the effects of various factors such as surface geometry and chemistry, liquids,

Thermodynamic analysis of chimney

International Journal of Exergy, 2009
Thermodynamic analysis, including energy and exergy, was applied for studying a chimney phenomenon. The mathematical model of a chimney was derived and used for evaluation of output trends responsive to change of some input parameters. It was proposed to use chimney efficiency as a measure of waste heat recovery.
