Fuzzy logic modeling of improvement of shell-andtube heat exchanger performance using ultrasonic waves abstract
In this work, the application of fuzzy logic (FL) modeling was investigated to predict the performance of a new type shell-and-tube heat exchanger, which works under the ultrasound field of 35 kHz transducer. Under ultrasonic conditions, the overall heat transfer coefficient was augmented significantly. Hot side and cold side volume flow rates were selected as inputs and overall heat transfer coefficient under ultrasound condition (Uus) and enhancement factor (EF) were taken as output parameters. Sixteen experimentally gathered data sets were used for modeling. A comparison between the fuzzy predictions and experimental data showed the accuracy and high capability of the model for predicting the outputs. Mean relative error and regression factor were 0.13% and 0.99985 for Uus and 0.02% and 1 for the EF. Based on the obtained results, the use of FL appears to be an accurate and simple way to model the performance of the shell-and-tube heat exchanger under the ultrasound field.
