Multiscale Hypersonic Boundary Layer Reconstruction via Spectral Binning and Subdomain-wise Conditional Diffusion
arXiv:2606.15023v1 Announce Type: cross Abstract: We propose a multiscale probabilistic reconstruction framework for hypersonic Couette flow, where near-wall states are inferred from limited top-wall observations using conditional diffusion model. The boundary layer is divided into overlapping wall-normal subdomains, and a single height- and Mach-conditioned Elucidating Diffusion Model (EDM) is trained jointly for M=6,7,8 to sample velocity, density, pressure, and temperature fields conditioned on a top-wall boundary slice. A soft overlap inpainting strategy assembles subdomain predictions int
The proliferation of advanced AI techniques, particularly conditional diffusion models, is enabling breakthroughs in complex scientific simulations and data reconstruction for high-speed phenomena.
This development allows for more accurate and efficient analysis of hypersonic flows, critical for aerospace engineering and defense applications, potentially accelerating design cycles and operational capabilities.
The ability to reconstruct complex physical states from limited data using AI fundamentally alters how high-Mach number fluid dynamics are studied and engineered.
