Abstract
Plate-fin heat exchangers are used in several industrial processes, especially in gas-to-gas applications such as cryogenics, micro-turbines, automobiles, chemical process plants, naval and aeronautical. To deal with conflicting objectives the multiobjective optimization is presented as an important tool for researchers, scientists and engineers. This work proposes a multiobjective application of a recent variant of differential evolution for the search of better and more reliable Pareto front solutions. Simulation results show the potential of the proposed method regarding the design of a plate-fin heat exchanger with two conflicting objectives. It has been observed that the multiobjective technique of the differential evolution variant presented better results for several evaluation metrics applied in comparison to the classical multiobjective differential evolution technique and the reference method of Non-Dominated Sorting Genetic Algorithm II. In comparison to the NSGA-II technique, MOTDE presented significant increase of capacity, diversity and convergence diversity. In comparison to the original MODE, MOTDE presented better capacity and diversity.
