Researchers have developed a novel framework using a conditional diffusion model to reconstruct hypersonic boundary layers from limited top-wall observations. This method divides the boundary layer into subdomains, employing a diffusion model trained across multiple Mach numbers to predict flow fields. A specialized spectral loss function is introduced to enhance the fidelity of generated fields, particularly preserving high-wavenumber content. The model demonstrates effectiveness in reconstructing instantaneous structures, spectra, and statistical profiles, while also providing uncertainty estimates. AI
