| Abstract | The optimal artificial neural network model for predicting the heat transfer coefficient and friction factor of the spirally fluted tube is considered. The experiment, nine test sections with different characteristic parameters of: helical rib height-to-diameter, ?/di = 0.12, 0.15, 0.19 and helical rib pitch-to-diameter, p/di = 1.05, 0.78, 0.63 are tested. The developed artificial neural network model shows the mean square error (MSE) of 0.0123 and the correlation coefficient (R) of 1.00 in modeling of overall experimental data set. The predicted results obtained from the optimize ANN model are verified with the testing experimental data and good agreement is obtained with errors of ?2.5%, ?15% for the Nusselt number and friction factor, respectively. In addition, the optimal ANN model results are found to be more accurate than the predicted results obtained from the published correlation. |
