An experimental study is carried out to estimate the heat transfer characteristics as a function of selected input parameters. The experimental study consists of a flat copper plate heater located in a wind tunnel, which includes a pulsating jet actuator injected into the stream at the entrance of the plate. This is a well-known typical film cooling application. An experimentally evaluated data set is prepared to be processed with the use of neural networks. A back propagation algorithm, the most common learning method for ANNs, is used for training and testing the network. The results of the experiments and the ANN predictions are in close agreements with errors less than 1%. This study showed that the ANNs could be used to effectively model the heat transfer on a flat plate subjected to a pulsating jet. (C) 2016 Elsevier Ltd.
