Abstract
Optimization of a bitubular heat exchanger in countercurrent configuration was studied, seeking the minimum possible volume while subjected to design constraints. Geometric and operational parameters of the heat exchanger were varied using genetic algorithms with 50 individuals and maximum evolutionary chain of 100. Crossover and mutation were set to 0.8 and 0.005, respectively. Three different cases were analyzed and compared to a case study available in literature. By neglecting pressure drop it was possible to reduce volume by 73.9%. When pressure drop was restricted, heat exchanger volume decreased by 11% and average pressure drop was reduced by 95%.
