The experimental data from the literature were used for training of feed forward artificial neural network with error back propagation technique. Different training algorithms have been applied with different hidden layers and nodes to train the network. It was observed that the heat transfer coefficients predicted was close to the experimental data within the maximum error of ± 20 %. If more exhaustive input data were fed then error would have become still lesser. It has been observed that some algorithms are very efficient with respect to training time in comparison to other algorithms.PDFenUniversity of PretoriaThermosiphonArtificial neural networkVertical thermosiphon reboilerHeat transferANNHeat transfer coefficientsNeural networksPresentation
