Minimization of entropy generation in flat heat pipe

International Journal of Heat and Mass Transfer, 2011
A thermodynamic model of flat heat pipe is developed based on the laws of thermodynamics. Major reasons for entropy generation, which is considered as a significant parameter on heat pipe performance, are temperature difference between hot and cold reservoirs, frictional losses in the flow of working fluid, and vapor temperature and pressure drop along

Entropy generation minimization (EGM) in magneto peristalsis with variable properties

Computer Methods and Programs in Biomedicine, 2020
This article featuring the peristaltic transport of viscous material with variable properties (i.e. temperature dependent viscosity and thermal conductivity) through curved configuration. Fluid saturating through porous channel walls of uniform space. Entropy generation consideration here is to analyze irreversibility aspects. Channel boundaries retain

Quantifying and minimizing entropy generation in AMTEC cells

IECEC-97 Proceedings of the Thirty-Second Intersociety Energy Conversion Engineering Conference (Cat. No.97CH6203), 1997
Entropy 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 in a Vertical Porous Channel

2022
This chapter is mainly focused on the minimization of the total entropy generation in a thermodynamic system, which concerns the heating of water when it passes through a saturated porous media. The heating process is assumed by an array of heating tubes immerged on the porous media and perpendicular to the water flow direction.

Entropy Generation Minimization in Nanofluid Flow

2015
Extensive studies can be found in the literature on the development of nanofluids and improvements of their thermofluid characteristics both theoretically and experimentally. On the contrary, most of the studies on nanofluids have been conducted from the first law of thermodynamics perspective.

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.
