Entropy Generation Minimization Analysis of Active Magnetic Regenerators [PDF]
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]
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]
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 ...

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 analysis of two immiscible fluids
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.

Entropy Generation Minimization of a Thermoelectric Cooler [PDF]
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 ...
