A <italic>Posteriori</italic> Multiobjective Self-Adaptive Multipopulation Jaya Algorithm for Optimization of Thermal Devices and Cycles

Abstract

This paper presents the multiobjective optimization aspects of three thermal devices and two thermodynamic cycles. The thermal devices considered are two-stage thermoelectric cooler, heat pump, and a plate-fin heat exchanger. The thermodynamic cycles considered are transcritical CO2 cycle and the irreversible Carnot power cycle. A posteriori is proposed, and it is applied for the multiobjective optimization of the selected thermal devices and cycles to obtain the sets of nondominated alternative solutions. The results of computational experiments obtained by the MO-SAMP Jaya algorithm are found to be better than those obtained by the latest reported optimization algorithms.
