Abstract

The unsteady flow field of the multi-element airfoil 30P30N at low Reynolds numbers was analyzed using a high-precision CFD method employing the Large Eddy Simulation (LES) turbulence model. Additionally, a reduced-order model (ROM) based on Proper Orthogonal Decomposition (POD) and Galerkin projection was developed and verified. This approach not only deepens our understanding of the aerodynamic performance of multi-element airfoil but also provides an efficient tool of reduced order modeling.
