Optimization of a Circular Microchannel With Entropy Generation Minimization Method

AIP Conference Proceedings, 2010
New 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.

Entropy Generation Minimization of Vapour Absorption Heat Transformer

2021
Vapour 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.

Production optimization of hydrocarbon reservoirs by entropy generation minimization

Journal of Natural Gas Science and Engineering, 2020
Abstract 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.

Entropy generation minimization of a MHD (magnetohydrodynamic) flow in a microchannel

Energy, 2010
The dissipative processes that arise in a microchannel flow subjected to electromagnetic interactions, as occurs in a MHD (magnetohydrodynamic) micropump, are analyzed. The entropy generation rate is used as a tool for the assessment of the intrinsic irreversibilities present in the microchannel owing to viscous friction, heat flow and electric ...

Entropy generation minimization on CIC (Cable-In-Conduit) superconductor design

Cryogenics, 1998
Abstract The concept of EGM (Entropy Generation Minimization) is applied to the design of an optimum CIC (Cable-In-Conduit) superconducting cable for large scale superconducting magnets, which is cooled by supercritical helium flow inside a conduit at cryogenic temperature.

Entropy Generation Minimization analysis of oscillating-flow regenerators

International Journal of Heat and Mass Transfer, 2015
Abstract The thermodynamic efficiencies of regenerative cooling cycles are directly linked to the heat transfer effectiveness and thermal losses in the regenerator. This paper proposes a performance analysis for regenerators based on the Entropy Generation Minimization (EGM) theory.
