Exergetic Efficiency Optimization for an Irreversible Carnot Heat Engine
Journal of Mechanics, 2007 AbstractIn this paper, an exergetic efficiency optimization method that combines the concept of exergy and finite-time thermodynamic theory is developed to analyze an irreversible heat engine. With the total thermal conductance constraint, the analytical solutions of optimal allocation of thermal conductance and the corresponding maximum exergetic ...

Optimization of Two-Stage Peltier Modules: Structure and Exergetic Efficiency [PDF]
Entropy, 2012 In this paper we undertake the theoretical analysis of a two-stage semiconductor thermoelectric module (TEM) which contains an arbitrary and different number of thermocouples, n1 and n2, in each stage (pyramid-styled TEM). The analysis is based on a dimensionless entropy balance set of equations.

Exergetic efficiency prediction of roughened solar air heater
Journal of Thermal Engineering, 2023 Energy losses of flowing air through solar air heater (SAH) duct does not consider in the ther-mal performance. Therefore, thermohydraulic performance based on exergetic efficiencies is a tool to assess the performance by considering energy losses in propelling the air simul-taneously to identify the best ribs configuration.
