Coherent structures in the boundary layer of a flat thick plate

We use POD and EPOD (extended POD) analysis to extract the mai n fe tures of the flow over a thick flat plate simulated with a LES. Our goal is to better understand the cou pling between the velocity field and the surface pressure field. We find that POD modes based on the full velocit y and energy fields contain both flapping and shedding frequencies… (More)
