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 ...

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 analysis of two immiscible fluids

open access: yesInternational Journal of Thermal Sciences, 2022
Abstract The entropy generation of two immiscible fluids is investigated in a conjugate heat transfer system. The velocity and temperature fields are analytically obtained by solving the momentum and energy conservation equations. These analytical solutions are used to calculate the local and total entropy generation rates.

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 ...

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 Generation Minimization of Two-Phase Flow Irreversibilities in Hydrocarbon Reservoirs

open access: yesEnergies, 2023
The efficient use of available energy in hydrocarbon extraction processes is essential to reducing overall emissions in the petroleum industry. The inefficient design of an extraction process leads to higher emissions per unit mass of hydrocarbon ...
