Patched Flow Matching: Generative Wall-Pressure Reconstruction Beyond Training-Domain Scales from Sparse Sensors
Meet Hemant Parikh, Yi Liu, Jian-Xun Wang
Characterizing the complete wall-pressure spectrum in turbulent wall-bounded flows requires simultaneous access to the viscous-scale high-wavenumber content and the outer-layer low…

D-Flow SGLD: Source-Space Posterior Sampling for Scientific Inverse Problems with Flow Matching
Meet Hemant Parikh, Yaqin Chen, Jian-Xun Wang
Data assimilation and scientific inverse problems require reconstructing high-dimensional physical states from sparse and noisy observations, ideally with uncertainty-aware posteri…
