Quantifying and minimizing entropy generation in AMTEC cells
IECEC-97 Proceedings of the Thirty-Second Intersociety Energy Conversion Engineering Conference (Cat. No.97CH6203), 1997Entropy generation in an AMTEC cell represents inherent power loss to the AMTEC cell. Minimizing cell entropy generation directly maximizes cell power generation and efficiency. An internal project is on-going at AMPS to identify, quantify and minimize entropy generation mechanisms within an AMTEC cell, with the goal of determining cost-effective ...

Entropy Generation Minimization of Vapour Absorption Heat Transformer
2021Vapour absorption heat transformers (VAHT) are thermally operated systems, capable of upgrading waste heat or any low-grade energy such as solar and geothermal energy into useful levels. This paper presents the entropy generation minimization analysis of vapour absorption heat transformer system with water/lithium bromide as working fluid pair.

The Method of Entropy Generation Minimization
1999The objective of this chapter is to review a modern transformation in the teaching, research and practice of energy engineering: the increasingly important roles played by thermodynamics (especially the second law) in problem formulation, modeling and design optimization.

Optimization of a Circular Microchannel With Entropy Generation Minimization Method
AIP Conference Proceedings, 2010New advances in micro and nano scales are being realized and the contributions of micro and nano heat dissipation devices are of high importance in this novel technology development. Past studies showed that microchannel design depends on its thermal resistance and pressure drop.

Production optimization of hydrocarbon reservoirs by entropy generation minimization
Journal of Natural Gas Science and Engineering, 2020Abstract Reservoir entropy generation has a significant role in production cycles of a hydrocarbon reservoir. During production, entropy generation characterizes the irreversible fluid energy losses. This paper aims to develop a new production strategy that minimizes the entropy production to improve operational efficiencies.
