Researchers have developed an extreme super-resolution framework using a deep learning model, WDSR, to reconstruct turbulent flow fields from a single high-resolution realization. This method involves training the network on overlapping patches of the flow and then reconstructing unseen fields through patchwise prediction and weighted assembly. The approach demonstrated improved accuracy in reconstructing coherent vortical structures and fine-scale features compared to conventional interpolation, even at severe spatial under-resolution factors of x32 and x64. This data-efficient technique shows promise for turbulent super-resolution when high-resolution training data is limited. AI
