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 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 rate minimization for sulfur trioxide decomposition membrane reactor
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]
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 ...
