Thermodynamic optimization of regenerators
Cryogenics, 1991This paper presents a second law of thermodynamics analysis technique for regenerators in single blow operation. Unlike earlier analyses, this technique accounts for the gas and matrix temperature variation along the temporal and spatial coordinates. The results of this study indicate that: 1, well defined optima exist with regard to charging time and ...

Thermodynamic optimization of the As–S system
Calphad, 2021Literature review, critical assessment and thermodynamic modeling of the liquid and solid phases in the As–S system are presented. A set of optimized model parameters was obtained to reproduce previously published experimental data. The literature data included enthalpies of formation, heat capacity, vapor pressure and phase equilibrium data.

Thermodynamic Optimization of the Cr-Ti System
International Journal of Materials Research, 2000A thermodynamic description of the Cr-Ti system is obtained by the optimization of the available thermodynamic and phase diagram data. The Redlich-Kister polynomial is used to describe the excess Gibbs energies of the liquid, bcc and hcp phases. The sublattice model is used to describe the different types of Cr2Ti Laves phases.

Thermodynamic Engine Optimization
2013In this chapter, we show how the capabilities of numerical simulations and theoretical finite-time thermodynamics tools complement each other to optimize the performance of a spark ignition engine. Numerical simulations enable us to check the influence of specific parameters in engine operation, whereas theoretical techniques allow us to suggest ...

Bioethanol Production Optimization: A Thermodynamic Analysis
Applied Biochemistry and Biotechnology, 2008In this work, the phase equilibrium of binary mixtures for bioethanol production by continuous extractive process was studied. The process is composed of four interlinked units: fermentor, centrifuge, cell treatment unit, and flash vessel (ethanol-congener separation unit).

Annealing placement by thermodynamic combinatorial optimization
ACM Transactions on Design Automation of Electronic Systems, 2004Placement is key issue of integrated circuit physical design. There exist some techniques inspired in thermodynamics coping with this problem as Simulated Annealing. In this article, we present a combinatorial optimization method directly derived from both Thermodynamics and Information Theory.

Thermodynamics guided lead discovery and optimization
Drug Discovery Today, 2010The documented unfavorable changes of physicochemical properties during lead discovery and optimization prompted us to investigate the present practice of medicinal chemistry optimization from a thermodynamic perspective. Basic principles of binding thermodynamics suggest that discriminating between enthalpy-driven and entropy-driven optimizations ...

Thermodynamic Optimization of the Co-Zn System
Journal of Phase Equilibria & Diffusion, 2004Literature information and authors’ experimental data have been used for the evaluation of optimized polynomial coefficients serving to calculate the cobalt (Co)-zinc (Zn) phase diagram. The programs BINGSS and THERMO-CALC have been used for the optimization.

Thermodynamic optimization in the Mg–Y system
Intermetallics, 2003Abstract New experimental measurements of mixing enthalpy and activity of the liquid phase along with the data already taken into account in previous thermodynamic assessments have been used in a reassessment of the thermodynamic parameters of the Mg–Y system.
