Diffuser and Nozzle Design Optimization by Entropy Generation Minimization

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 coefficientK, which can be linked to the overall entropy generation due to the conduit component. First, a polynomial shape of the wall with two degrees of freedom is assumed. As a second approach six equally spa...

Comparison of entropy generation minimization principle and entransy theory in optimal design of thermal systems

In this study, the relationship among the concepts of entropy generation rate, entransy theory, and generalized thermal resistance to the optimal design of thermal systems is discussed. The equations of entropy and entransy rates are compared and their implications for optimization of conductive heat transfer are analyzed. The theoretical analyses show that based on entropy generation minimizat...

Optimization of Double Pipe Fin-pin Heat Exchanger Using Entropy Generation Minimization

In the current work optimization of double pipe fin-pin heat exchanger has been studied. The effective parameters those are controlling the heat exchanger performance are divided in two categories; geometrical and operating conditions. Using the Brent’s optimization algorithm and handling the thermodynamically design concept, one can minimize entropy generation in different length of heat excha...

Reliability of Heat Sink Optimization Using Entropy Generation Minimization

The design and optimization of electronics cooling systems is not easily accomplished through conventional analysis tools such as analytical and numerical methods. The enhancement in thermal performance causes a rise in pressure drop, which increases the load of pumping power. Consequently, the overall assessment of cooling system requires a trade-off between thermal performance and pressure dr...

Entropy Generation Minimization of a Thermoelectric Cooler

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 Thermodynamics to a TEC. We consider the entropy generation equation as the objective function and the first law as a restriction, in accordance with the variational calculus...
