Entropy Generation Minimization for Energy-Efficient Desalination [PDF]

open access: yesVolume 6B: Energy, 2018
Desalination systems can be conceptualized as power cycles, in which the useful work output is the work of separation of fresh water from saline water. In this framing, thermodynamic analysis provides powerful tools for raising energy efficiency.

Entropy Generation Minimization Analysis of Active Magnetic Regenerators [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2017
A performance assessment of active magnetocaloric regenerators using entropy generation minimization is presented. The model consists of the Brinkman-Forchheimer equation to describe the fluid flow and coupled energy equations for the fluid and solid ...

Multi-Objective Constructal Design for Square Heat-Generation Body with “Arrow-Shaped” High-Thermal-Conductivity Channel

open access: yesEnergies, 2022
Based on the square heat-generation body (HGB) with “arrow-shaped” high-thermal-conductivity channel (HTCC) model established in the previous literature, we performed multi-objective optimization (MOO) with maximum temperature difference (MTD ...

Diffuser and Nozzle Design Optimization by Entropy Generation Minimization [PDF]

open access: yesEntropy, 2011
Diffusers and nozzles within a flow system are optimized with respect to their wall shapes for a given change in cross sections. The optimization target is a low value of the head loss coefficient K, which can be linked to the overall entropy generation ...

Entropy Generation Minimization Theoretical Analysis for External Flow Around Horizontal Cylinder at low Reynold Number [PDF]

open access: yesEngineering and Technology Journal, 2018
The minimization of entropy generation is a helpful method to design optimum thermal system, and find an expression for entropy generation at several ranges of Reynolds number for heat transfer and friction flow irreversibility is a good way to achieve ...

Entropy generation rate minimization for sulfur trioxide decomposition membrane reactor

open access: yesEnergy Reports, 2022
Sulfuric acid decomposition is the critical reaction in sulfur-iodide thermochemical cycle to produce oxygen. Sulfuric acid can decompose spontaneously into sulfur trioxide (SO3) and water, and SO3 continues to decompose into oxygen and sulfur dioxide ...

Entropy Generation Minimization of a Thermoelectric Cooler [PDF]

open access: yesThe Open Thermodynamics Journal, 2008
In the present work, we develop a theoretical analysis to minimize the entropy generation of a thermo-electric cooler (TEC), which can be used to cool a processor. We have applied an analysis of first and second law of the Thermo- dynamics to a TEC. We consider the entropy generation equation as the objective function and the first law as a restric ...

Entropy Analysis of the Thermal Convection of Nanosuspension within a Chamber with a Heat-Conducting Solid Fin

open access: yesEntropy, 2022
Heat transport augmentation in closed chambers can be achieved using nanofluids and extended heat transfer surfaces. This research is devoted to the computational analysis of natural convection energy transport and entropy emission within a closed region,

Miller cycle analysis using EGM [PDF]

open access: yes, 2005
The Entropy Generation Minimization (EGM) method is based on the analysis by three sciences (thermodynamics, fluid flow and heat transfer) of the different processes that may occur in a system or in an equipment.
