Fig. 12From: POD-Galerkin reduced order models and physics-informed neural networks for solving inverse problems for the Navier–Stokes equationsThe first two POD modes of the velocity and pressure, a 2D cross-sectional view of the domain at \(x_3 = L\) is shown. (a) The first velocity POD mode. (b) The second velocity POD mode. (c) The first pressure POD mode. (d) The second pressure POD modeBack to article page
