Deep convolutional autoencoder augmented CFD thermal analysis of bearings with inter pad groove mixing

•Bearing groove model via a deep convolutional autoencoder training based on CFD data.•Consideration of 2D temperature distribution at pad leading edge of fluid-film.•Combination of rotor-bearing model and convolutional neural network.•Proposed model validation through comparison to full CFD and available test data.•Accurate heat transfer and temperature prediction for a rotor-bearing system.
