Abstract:
In the present study, a hybrid deep learning reduced order model (ROM) is applied for unsteady transonic wing buffet load prediction. The hybrid model is defined by the combination of a convolutional variational autoencoder (CNN-VAR-AE) and a long short-term memory (LSTM) neural network. In the first step, the CNN-VAR-AE is trained using experimental buffet data. Thereby, the high-dimensional buffet flow field is reduced into a low-dimensional latent space. In the second step, the LSTM is traine...     »
