WebMar 4, 2024 · We have analyzed two trained physics-informed models: a supervised model based on convolutional neural networks (CNN) and a generative model based on SRGAN: Turbulence Enrichment GAN (TEGAN), and show that they both outperform simple bicubic interpolation in turbulence enrichment. WebA three-dimensional convolutional variational autoen- coder is developed for the random generation of turbulence data. The varational autoencoder is trained on a well- resolved simulated database of homogeneous isotropic tur- bulence. The variational autoencoder is found to be suffi- cient in reconstructing a non-trivial turbulent vector field.
