Fuzzy Logic Modeling of Heat Transfer in an Air Cooler Equipped with Butterfly Insert

A. Karami, E. Rezaei, M. Shahhosseni, and S. Feiz Jafari

Abstract—This paper highlights the use of fuzzy logic to model and predict the experimental results of heat transfer in an air cooled heat exchanger equipped with the butterfly inserts. Experiments included Reynolds number ranging from 4021 to 16118 and the inclined angle of the butterfly inserts from 45◦ to 90◦. Experimental results showed that, the maximum heat transfer by the use of butterfly insert was obtained with the inclined angle of 90◦. A fuzzy inference system named Mamdani was used to expect the output membership functions to be fuzzy sets. It has been also shown that, fuzzy logic is a powerful instrument for predicting the experiments due to its low error. The average error of fuzzy with respect to experimental data was found to be 0.41% for this study.

Index Terms—Air cooled heat exchanger, Fuzzy logic, Heat transfer, Mamdani inference system, Butterfly inserts.
