Data-Driven Modal Decomposition Analysis of Unsteady Flow in Multistage Turbine

Two data-driven modal analysis approaches, proper orthogonal decomposition (POD) and dynamic mode decomposition (DMD), are applied to analyze the unsteady flow obtained by solving the Reynolds-averaged Navier–Stokes (RANS) equations in a 1.5-stage axial turbine. The reduced-order...
