A genetic algorithm optimization for a finned channel performance

Compared to a smooth channel, a finned-channel provides higher heat transfer coefficient and increasing the fin height enhances the heat transfer. However, this heat transfer enhancement is associated with an increase in the pressure drop. This leads to an increased pumping power requirement so that one may seek an optimum design for such systems. The main goal of this paper is to define the exact location and size of fins in such a way that a minimal pressure drop coincides with an optimal heat transfer based on the genetic algorithm. Each arrangement of fins is considered as a solution of the problem (an individual for genetic algorithm). An initial population is generated randomly at the first step. Then the algorithm has searched among these solutions and made new solutions iteratively by its functions to find an optimum design as reported in this article
