The main aim of this work is devoted to numerical optimization of fin–pin arrangement in the double pipe heat exchanger. For this reason, heat exchanger which is used by Sahiti et al. was studied as an initial geometry. Since they did not consider the fin–pin arrangement effects, modification of their model by changing the fin arranges and using the Brent’s optimization algorithm based on the thermodynamically design concept, would be useful. In this work, by minimizing the entropy generation in constant heat duty per length and constant fins diameters D and changing the pin’s longitudinal (SL) and transversal (ST) distances, better results have been achieved. Results showed that, in all conditions entropy generation number decreased and consequently leads to reduction in pumping power and manufacturing costs.
