Estimation of Time Dependent Flow Properties in an Open Cavity

摘要: Experiments have been performed to measure the velocity field and surface pressure synchronously for flow over an open cavity. Specifically, l/d = 6 full span cavity with a Mach 0.6 free stream turbulent boundary layer at cavities leading edge was studied. The study focuses on using these measurements in mean-square estimation technique time dependence of low-dimensional formulation field. Utilizing select modes from Proper Orthogonal Decomposition technique, features associated Rossiter were reconstructed. dependent estimated demonstrates how shear structures interact aft wall form source intense areoacoustic environment known exist flows.Copyright © 2005 by ASME
