Sažetak
In this study an optimisation of a plain fin- and-tube heat exchanger (FTHE) has been performed. Combination of response surface methodology and genetic algorithm is applied to search for optimal geometry configuration of FTHE [1, 2]. The aim of this work was to obtain optimal geometry which yields maximal heat transfer as well as minimal pressure drop. Four geometry parameters have been optimized: longitudinal and transversal tube pitches, fin thickness and fin pitch. Colburn j-factor and friction factor f are taken as objective functions. The finite volume method, implemented in CFD software Ansys Fluent, was used to solve mathematical model of fluid flow and heat transfer. Central composite design method (CCD), combined with the finite volume method, has been applied to calculate objective functions. Based on obtained numerical results, Colburn and friction factors have been calculated for thirty-one different parameter combinations. Additionally, genetic algorithm is utilized in order to optimize the objective functions obtained by response surface methodology.
