Researchers have developed a patch-based 3D variational autoencoder (3D-VAE) to improve the super-resolution of turbulent channel flow simulations. This method reconstructs fine-scale flow structures from coarser data, addressing the computational expense of direct numerical simulations at high Reynolds numbers. The 3D-VAE model, trained on data from the Johns Hopkins Turbulence Database, demonstrated a threefold reduction in spectral space error compared to traditional interpolation methods and showed potential for reconstructing spectral content absent in filtered simulations.
