DD-RNO: A Domain-Decomposed Routed Neural Operator for Airfoil Flow Prediction
Deep learning surrogates for RANS flow prediction around airfoils face two persistent bottlenecks: sharp near-wall boundary layers and smooth far-field potential flow, and numerical instability of computing wall-normal velocity gradients from continuous-field approximations.
