SS-POD augments standard POD-Galerkin with a spectral-subspace partition and local POD to achieve lower out-of-sample error than either plain POD or pure spectral-Galerkin when only a handful of snapshots are available.
A hybrid MRI-PINN-resolvent framework extracts mean fields from stenotic flow measurements and identifies stationary eigenmodes in the recirculation bubble plus broadband pseudo-resonance in the shear layer.
Rarefied hypersonic bow shocks over a cylinder inflate via multi-scale compression-relaxation with density becoming nearly rank-one while Mach and thermal fields retain independent modes, as separated by Knudsen and Mach sweeps in DSMC data.
2D DES simulations show a feedback-driven pressure oscillation loop in transonic cavity-sub-cavity flows that is most suppressed by a slotted sub-cavity design.
