Summary

In this work, two optimization criteria, minimum weight and minimum entropy generation, are simultaneously applied to deduce the main geometric characteristics of the two finned cross-flow heat exchangers that the environmental control system (ECS) of commercial aircraft normally incorporate. The performance of this system, described and modelled in this paper, is optimized as a whole instead of considering the optimal operation of isolated devices. The ECS is based on Brayton inverse cycle, where two air streams are involved, one to be conditioned (the main stream), and a coolant one. Once the parameters and variables are identified, the optimization task would lead to optimal geometry by means of a trade-off solution.
