摘要：
Results are presented for the numerical simulation of unsteady viscous incompressible flow past thick airfoils. Specifically, flow past a NACA 4424 at an angle of attack of 2.5 deg and Reynolds numbers in the range of 1700-4000 has been simulated using the spectral element method. At these conditions the flow is separated and an unsteady wake is formed. Application of the method of empirical eigenfunctions reveals the structures of the most energetic components of the flow.
