Abstract : Unsteady two- and three-dimensional flow structure at leading- and trailing-edges of bodies can be characterized effectively using recently developed techniques for acquisition and interpretation of flow visualization. The techniques addressed herein include: flow image-surface pressure correlations; three-dimensional reconstruction of flow structure from flow images; and interactive interpretation of flow images with theoretical simulations. These techniques can be employed in conjunction with: visual correlation and ensemble-averaging, both within a given image and between images; recognition of patterns of flow structure from images; and estimates of velocity eigenfunctions from images.
