Abstract
In this work, a plate-fin heat exchanger is optimized through the Adaptive Differential Evolution JADE method. The plate-fin heat exchangers are widely used in industrial applications such as cryogenics, microturbines, vehicle and various chemical process. This heat exchanger topology has high thermal efficiency, high heat transfer area per unit volume and high thermal conductivity. Adaptive Differential Evolution JADE is an evolutionary algorithm with self-adjustable parameters derived from the differential evolution. This method, presented to the scientific community in 2009, has a mutation strategy based on the neighborhood and an optional external file aiming to improve the convergence of the method of differential evolution. The traditional approach of the design of this heat exchanger involves several geometric parameters and operational constraints. The geometric parameters used in the optimization were heights, thicknesses, lengths, fin density and the amount of overlap of fins and the operational restriction of amount of heat to be exchanged. The optimization aimed the minimization of the total annual cost of the plate-fin heat exchanger and their results were compared with the Genetic Algorithm (GA) and Particle Swarm Optimization (PSO). The results of the 50 independent experiments demonstrate improvements up to 11.80% when compared to the GA and up to 10.93% when compared with the PSO.
